摘要： A system and methods for co-site and multi-path interference mitigation are presented. A reflection signal is received from at least one aircraft surface at a sensor near a receiver antenna, and a conformal reflective phased array antenna coupled to at least one aircraft surface is configured to steer the reflection signal. The reflection signal is steered using the conformal reflective phased array antenna to reduce an amplitude of the reflection signal at the receiver antenna based on the reflection signal received at the sensor.

摘要： A system and method for a self calibrating conformal phased array are disclosed involving a plurality of transmit/receive elements; a plurality of embedded, calibration transmit/receive elements scattered across the array; and at least one back-end processor. The calibration transmit/receive elements are used to track any physical calibration transmit/receive element's relative position change caused by array flexure. In one or more embodiments, each of the calibration transmit/receive elements transmit a tone using a small antenna, and the other calibration transmit/receive elements receive the tone using small antennas. The calibration transmit/receive elements that receive the tone measure the phase of the received tone. At least one back-end processor uses the measured phases to determine differential phases from a phase calibration table. Also, at least one back-end processor uses the differential phases to compute a change in apparent location of each transmitting calibration transmit/receive element.

摘要： A cooperative geolocation system and method. The system and method involves time stamping a plurality of received signals and modifying, such as compressing, one or more of the received signals, either with the same or with different rates of compression. A processing subsystem including a geolocation processor is used to correlate various pairs of received signals and to extract time difference of arrival (TDOA) or frequency difference of arrival (FDOA) information and to use this information in cooperatively geolocating the signal source emitting the signals being analyzed. The system enables greater rates of data compression, and thus frees up bandwidth in a network in which it is employed, as compared with previously existing cooperative geolocation systems. The present system further can perform the cooperative geolocation determination without first decompressing the compressed signals, but rather performing a correlation process directly on designated pairs of signals to extract the needed TDOA/FDOA information.

摘要： A non-contact biometric sensing device is described. The device includes a processing device, a user interface communicatively coupled to the processing device, a display communicatively coupled to the processing device, a laser doppler vibrometer sensor communicatively coupled to the processing device, and an infrared camera communicatively coupled to the processing device. The processing device is programmed to utilize mechanical motion data received from the laser doppler vibrometer sensor and thermal distributions data from the infrared camera to calculate biometric data, when signals originating from the laser doppler vibrometer sensor and the infrared camera are reflected back towards the device from a target.

摘要： A bank of order statistic filters applied to a set of antenna or transducer beams are used to detect and determine the line-of-bearing to the source of transient RF (or other, e.g., acoustic) signals. By applying order statistic filters to signals received by a set of antenna or transducer beams, this system sets a detection threshold that is unaffected by transient signals, thereby allowing the detection of these transient signals. Knowing which antenna beam the transient signals are located within allows the determination of a line of bearing to the source of the transient signals.
