OPTICAL PROCESSOR FOR SYNTHETIC SPECTRUM DATA
Abstract
A film recorder for high resolution radar echoes has been designed and fabricated. It employs a modulated cathode ray tube trace which is imaged onto a moving film. Individual pulse echoes are written across one dimension of the film, corresponding to the direction of the CRT sweep. Successive echoes are accumulated side-by-side in the orthogonal direction. The data is recorded in a format suitable for subsequent processing in a coherent optical system. The purpose is to obtain doppler resolution by integration over a sequence of pulses. This is to be carried out simultaneously for each range resolution element, giving an output with two dimensions of resolution. The specifications, design, fabrication, and check-out of the film recording equipment are described in this report. Simulated data has been employed to verify the overall performance of the device. A review is given of the data frames recorded and the test results obtained from them. The system can record data in two different formats, to allow some flexibility in implementing the coherent imaging processor.
