Applications of Acousto-Optical Correlation Devices in Radar Signal Processing
Abstract
This article, from the angle of experimentation, investigated the actual efficiency of acousto-optical correlation devices in radar signal processing. As far as centimeter wave band (3GHz) single carrier frequency square pulse radar signals and unmodulated random wave interference is concerned, it measured different pulse widths, different signal-to-noise ratios and, for these periods of time, the height of correlation peaks as well as the size of the correlation gain when there were different pulse widths. When the pulse width was 2.5 micro s, the correlation gain was 30dB. When the pulse width was 0.5 micro s, the correlation gain was 23dB. As far as the correlation peaks of acousto-optical correlation device outputs are concerned, they were all several score mV or higher. It was not necessary to go through any amplification. Rather, it was possible to make use of an oscillascope to directly carry out observations and measurements. Chinese translations. (rrh)
