    摘要: An electrical device functions as a thermally energized DC power source. The device has a base plate of conductive metal. A number of electrode points protrude upward from the base plate, terminating in a sharp edge. A collection plate of conductive metal is positioned above the sharp upper edges of the electrode points. The gap between the electrode points and between the collection plate and the electrode points is electrically insulated. An electrical potential exists between the base plate and the upper collection plate while the device is at and above room temperature. The potential difference increases as the temperature increases.

    摘要: A device will detect man-made objects by using a polarizer mounted to a video camera. The polarizer rotates about an axis in front of a lens array of the video camera. The rotation of the polarizer alternately polarizes light received in proportion to the speed of rotation. This produces flashing in intensity for detecting the object as well as background rejection due to its lack of polarization. A man-made object having both horizontal and vertical surfaces of a type that will reflect light that can be polarized will provide flashing through the lens array as the polarizer passes through horizontal and vertical position. On the other hand, backgrounds don't have polarized components and won't flash. Attention is drawn to the man-made target. A high pass filter between the video signal processor and the monitor reduces background from the observed scene, permitting precise lock-on to the target.

    摘要: A method and system of image modulation detection of an aircraft or missile exhaust plume or explosives by time sequence differentiation is provided. The method comprises the steps of forming two sequential images of the field of view in which an exhaust plume to be detected is located, and forming a differential image from the sequential images showing components of the aircraft's exhaust plume that are modulating at a rate greater than the frame rate of the detection system. The detection system permits a selection of frame rates so that unwanted (non-modulating) items in the field of view may be eliminated from detection by the threat warning system. The nonmodulating components such as the sky, hills, and even the missile body are eliminated from the differential image. Only the plume remains and only the plume is detected. Each image is formed by a plurality of pixels, wherein each pixel images a portion of the field of view. The value of each pixel in one sequential image is subtracted from the value of the corresponding pixel in the other sequential image to produce a value for a resultant pixel. The differential image is formed by imaging the resultant pixels that have a non-zero value, wherein the differential image shows components of the aircraft's or missile's exhaust plume that are modulating at a rate greater than the frame rate of the detection system. If false targets are detected by the system, the frame rate may be increased to decrease the time period between the formation of the first and second sequential images thereby eliminating targets having a lower modulation frequency.

Therefore there is not false alarm note. Each image is formed by a plurality of pixels, wherein each pixel images a portion of the field of view. A value is assigned to each pixel in each of the sequential images that corresponds to one or more characteristics of the pixel. The value of each pixel in one sequential image is subtracted from the value of the corresponding pixel in the other sequential image to produce a value for a resultant pixel. The differential image is formed by imaging the resultant pixels that have a non-zero value, wherein the differential image shows components of the aircraft's exhaust plume that are modulating at a rate greater than the frame rate of the detection system.

    摘要: A method for detecting objects while eliminating unwanted background utilizes polarizing contrasts. A lens systems focuses light from the field of view through a beam splitter. One beam passes to a digitizer through a polarizer which polarizes the beam at one angle. The other beam is reflected to another polarizer, which is located at a 90.degree. angle relative to the first polarizer. The pixels from the polarized images are digitized. A processor compares the corresponding pixels, subtracting one from the other to find a polarizing contrast. A range that can be varied will display only those pixels which have polarizing contrasts within the selected range. The selection of the range will either include or eliminate the background while displaying man-made targets.

    摘要: A detection system will detect targets against a fixed background if the target is of a type emitting a gaseous plume. The detection system directs electromagnetic energy, preferably radio frequency signals, toward the fixed background in an area of suspected target activity. The detection system has a receiver which detects reflected electromagnetic energy from the fixed background. The system will identify anomalous variations in range. The variations occur as a result of refraction of the electromagnetic energy wave passing through the gaseous exhaust stream. This indicates a probable target which is creating exhaust plume.

    摘要: A detection system will detect and identify self-propelled objects, such as missiles, which create a hot exhaust plume. The exhaust plume has radiation which modulates with a frequency range of interest. This frequency range can be detected with various detectors, such as an infrared detector, an ultraviolet detector, or even a radio frequency detector. Guided missiles have radiation frequencies which are much higher than the radiation frequencies of jet aircraft and of reciprocating engines. A filter will filter the output signals from the detector, and discard those outside of the frequency range of interest. A warning signal will indicate if frequencies are encountered within the frequency range of interest.

    摘要: A laser device utilizes a turbojet engine to provide a stimulation source. The turbojet engine is conventional, having a compression section, a fuel injection and igniting section, and an afterburner section. A pair of mirrors are mounted adjacent the hot gaseous stream produced by the turbojet engine. One of the mirrors is fully reflective and the other is partially reflective. The mirrors face each other and are perpendicular to the flow of the gaseous stream, creating a reflection path that is transverse to the flow. The high temperature creates excited molecules in the gaseous stream. This results in photons being emitted, which when striking other excited atoms which emit photons of the same wavelength, create additional photons to combine into a laser beam travelling along a reflection path between the mirrors. A portion of the laser beam passes through the partially reflecting mirror where it strikes an inclined mirror that aims the beam toward a desired target.
