Abstract: A technique is provided for passively detecting the presence and location of an underground object. A plurality of individual antennas positioned in a linear array are directed to receive fields of view which are mutually parallel in azimuth. The linear array is then focused at a plurality of different angles in azimuth for passively acquiring low level random noise signals in the RF spectrum which are emitted by the underground object and by the intervening media. A radiometric receiver receives the noise signals acquired by each of the antennas as a separate channel, digitizes them and forwards them to a signal processor which performs a number of operations including:a mathematical integration for each separate channel received by the radiometric receivers;the generation from each of the integrated channels of a plurality of simultaneous digitally synthesized electromagnetic fields of view;directing the plurality of electromagnetic fields of view at a plurality of different spatial angles;performing an autocorrelation operation on each of the integrated channel responses;computing an inverse Fourier transform on the result of the autocorrelation operation on each of the integrated channel responses; andgenerating a spectrograph therefrom presenting power as a function of frequency.From all of the foregoing, the system of the invention is able to determine the location and depth of the underground object.

Abstract: A passive rangefinder for determining the range to an object such as an aircraft, rocket or missile which emits electromagnetic radiation makes use of spectral measurements over a broad band of frequencies. The rangefinder includes means 202 for forming a real image of a field of view, spectrophotometer means 201 including an entrance aperture 27 placed to receive at least a part of said real image, dispersion means (15, 28, 29) for separating radiation of different wavelengths and detector means 24 for measuring the spectrum of radiation received from distinct portions of the entrance aperture. The detector output is connected to data processing means 204 arranged to deconvolve the received spectral profile with a stored representation (205) of a range-dependent atmospheric transmission spectral profile to obtain a representation of the spectral emission profile of radiation from the object. From the emission spectral profile a characteristic temperature of emission (206) is derived and hence a Planck emission spectrum for the object. The Planck spectrum is used to determine the range from the calculated emission spectrum and the observed spectrum (205, 208). Thus by deconvolving the measured spectrum with the atmospheric transmission spectrum the range can be determined. The invention can work at any range of e.m. radiation for which suitable components are available. Advantageously the ranging is done on two different temperature portions of the same object so that different Planck profiles are used in the signal processing. The atmospheric transmission spectrum can be measured prior to operation in the prevailing conditions by use of a laser rangefinder.

Abstract: Methods for determining integrity of pseudorange and pseudorange rate signals received from a plurality of M Satellite Positioning System satellites (including GPS and GLONASS), numbered j=j1, j2, . . . , jM, at a reference SATPS station (RS), using pseudorange or pseudorange rate signals received from the same satellites at a nearby signal integrity monitoring (SIM) station. Pseudorange correction values or, alternatively, pseudorange rate correction values, for SATPS signals received at an RS station and at the corresponding SIM station are computed, and difference values between the RS and SIM values are computed for each satellite. If the magnitude of each difference is less than a selected threshold difference, pseudorange corrections or pseudorange rate corrections for that reference station can be used by a nearby mobile station to differentially correct the mobile station location fix coordinates or velocity fix coordinates. If N acceptable pairs of difference values are found for the pseudorange or pseudorange rate corrections, for particular satellites: clock bias or frequency offset can be corrected if N.gtoreq.1; accuracy of the clock bias or frequency offset coordinate can be monitored if N.gtoreq.2; and location fix coordinates or velocity fix coordinates can be corrected if N.gtoreq.3. If magnitudes of differences between measured and known location coordinates or velocity coordinates for the SIM station are less than threshold differences, pseudorange corrections or pseudorange rate corrections for that reference station can be used by a nearby mobile station to differentially correct the mobile station location fix coordinates or velocity fix coordinates.

Abstract: A radar range finder and hidden object locator is based on ultra-wide band radar with a high resolution swept range gate. The device generates an equivalent time amplitude scan with a typical range of 4 inches to 20 feet, and an analog range resolution as limited by a jitter of on the order of 0.01 inches. A differential sampling receiver is employed to effectively eliminate ringing and other aberrations induced in the receiver by the near proximity of the transmit antenna, so a background subtraction is not needed, simplifying the circuitry while improving performance. Uses of the invention include a replacement of ultrasound devices for fluid level sensing, automotive radar, such as cruise control and parking assistance, hidden object location, such as stud and rebar finding. Also, this technology can be used when positioned over a highway lane to collect vehicle count and speed data for traffic control.

Abstract: Transmitted signals are used to accurately and remotely determine the veral distance of an earth-based receiving antenna above a surface, and hence can be used to determine the tide condition of a water surface. A signal is transmitted from a signal source as it moves either through air or space. An antenna whose height is to be determined with respect to a reflecting surface, such as water, receives the signal directly from the signal source and indirectly from the signal source by reflection of the signal from the reflecting surface. The sum of the directly and indirectly received signals form an interference pattern as the signal source is moved. Points on the interference pattern are selected at identical phase angle for each cycle of the pattern. The points are assigned reference numbers and the numbers are plotted with respect to a measurement indicative of the distance between the signal source and the antenna whose height with respect to the reflecting surface is to be determined. The slope or gradient of the reference numbers with respect to this measurement is determined. Reference interference patterns are generated either through mathematical modelling and/or through direct physical measurement and these are used to establish an equation relating known antenna-to-surface distances to the slopes of the reference numbers verses measurement. The slope corresponding to the antenna of an unknown distance from a surface is inserted into this equation and the equation is solved for the unknown distance.

Abstract: Methods for determining the integrity of pseudorange and pseudorange rate signals received from a plurality of M Satellite Positioning System satellites (SATPS, including GPS and GLONASS), numbered j=j1, j2, . . . , jM, at a reference SATPS station (RS), using pseudorange and pseudorange rate signals received from the same satellites at a signal integrity monitoring (SIM) station located near the reference station. Pseudorange correction values PRC(t;i;j).sub.RS and PRC(t;i;j).sub.SIM and pseudorange rate correction values PRRC(t;i;j).sub.RS and PRRC(t;i;j).sub.SIM for the signals received at the reference station (RS, number i) and at the SIM station are computed, and difference values DPRE(t;i;j)=PRC(t;i;j).sub.RS -PRC(t;i;j).sub.SIM and DRRE(t;i;j)=PRRC(t;i;j).sub.RS -PRRC(t;i;j).sub.SIM are computed from these correction values.

If at least one acceptable pair of difference values DPRE(t;i;j) and DPRRE(t;i;j) is found, for a particular satellite j, clock bias and frequency offset can be corrected using the SATPS signal received from that satellite at the SIM station. If at least two pairs of difference values DPRE(t;i;j) and DPRRE(t;i;j) are acceptable, for satellites j1 and j2, the accuracy of the clock bias and frequency offset parameters can be monitored using the SATPS signals received from that pair of satellites. If at least three pairs of difference values DPRE(t;i;j) and DPRRE(t;i;j) are acceptable (for three distinct satellites), the location coordinates and/or velocity coordinates can be corrected using the signals received from those satellites, if a precise SIM station clock is provided; otherwise, at least four acceptable pairs of difference values are required.

Abstract: A range finding system uses non-simultaneous measurements between two communicating and cooperating instruments such that a single carrier frequency is used to exchange information between the instruments with non-simultaneous transmission using the same transmission channel. The range finding system may be considered to be an interrogator/transponder arrangement in which the results of a phase measurement against a local clock is made at one transponder station during one time interval, and then the transponder transmits both a tone derived from the transponder's local clock and the measurement results back to the interrogator station during a second time interval. The interrogator then has everything it needs to accurately compute the range while eliminating local delays in clock differences, while permitting the interrogator and the transponder to share a single frequency intermittently.
