摘要： In an optical radar system a coherent signal is transmitted at a variable position and the return signal, that is, the reflected portion of the coherent signal is received and coherently detected. The transmitter utilizes a scanning laser having an electron beam that impinges upon a variable reflectance mirror that terminates one end of an optical cavity. An oscillating mode is generated within the resonant cavity when the electron beam locally heats the surface of the variable reflectance mirror to create a pixel that reflects light in a diffracted pattern. The receiver utilizes a stable single mode laser to illuminate a variable reflectance surface. A receiver electron beam generates a plurality of receiver pixels at various positions. The diffracted light from each pixel generates a plurality of variable angle local oscillator beams that are summed with the return signal at a beamsplitter. The output of the beamsplitter is applied to the surface of a detector array. One of the local oscillator beams is positioned such that the return signal and the local oscillator beam overlap at one of the detectors in the array to provide coherent detection. The frequency of the first coherent signal and the second coherent signal are sampled by a first and second partially reflecting mirror. A frequency detector detects the output of the first and second partially reflecting mirror to detect the frequency difference between the first and second coherent signal and generate a control signal that adjusts the frequency of the first coherent signal. For heterodyne operation a selected frequency difference is generated whereas for homodyne detection a zero frequency difference is generated. An electronic computer coordinates the position of the scanning laser of the transmitter and the position of the local oscillator beams of the receiver such that one of the local oscillator beams will overlap with each of the corresponding return signals at the detector array. A second electronic computer processes the output of the detector array to provide information about the return signal.

摘要： Provided is a method and apparatus for deploying an inflatable antenna from a compressed storage position on the trailer bed of a transport vehicle. A support structure is provided having a pair of spaced apart actuating rails for engagement with the antenna during deployment and a storage compartment stored on the trailer bed of the transport vehicle. The storage compartment is formed of a base wall which is pivotally affixed to both the trailer bed and one end of the compressed antenna, and a deployment structure affixed to the opposing end of the compressed antenna. The deployment structure is partitioned lengthwise to form first and second shelter compartments which are hinged together at one end and pivotable with respect to one another between a closed storage position and an open A-frame position. The shelter compartments further have engaging means for engagement with the support structure actuating rails when opened to the A-frame position to pull the deployment structure and the compressed antenna away from the base wall while inflating the compressed antenna. In operation, the base wall and the deployment structure are elevated from the trailer bed and the deployment structure is disengaged from the base wall. Thereafter, the deployment structure is positioned on the support structure and the shelter compartments are pivoted about their hinged axis and secured in an open cantilevered position. The shelter compartments are thereafter engaged with the support structure and pulled away from the base wall while the antenna is inflated.

摘要： The present invention relates to an optical reimaging system which incorporates multiple sets of lenses to transmit an image from one plane to another in the form of image segments which are detected by one or more discrete detector arrays. Signals generated by the detector array or arrays can be used to recombine the image segments to reproduce the image transmitted from the first focal plane. These image segments can be contiguous or separated, inverted or not, depending on the lens arrangment and magnification used. In infrared applications, all or a portion of the reimaging system may be cooled to reduce contaminating warm radiation.

摘要： A computerized flight inspection system is disclosed. The system of the present invention may be utilized to generate an accurate reference location with respect to an airport runway for an aircraft having an inertial navigation system. A selected geometric pattern having a highly unambiguous autocorrelation function is placed on at least one end of the runway. A video line scanning camera mounted to the aircraft is then utilized to scan the geometric pattern in a line generally perpendicular to the line of flight. The output of the video line scanning camera is then correlated with a stored reference pattern to generate a signal indicative of the detection of the geometric pattern on the runway. A laser altimeter is mounted to the aircraft and utilized to generate an accurate signal indicative of the aircraft altitude with respect to the runway pattern. The outputs of the correlation circuit and the laser altimeter are then utilized to correct data from the inertial navigation system.
