A THEORETICAL ANALYSIS OF A COMPRESSED-TIME CORRELATOR FOR SIGNAL DETECTION
用于信号检测的时间压缩相关器理论分析

The theoretical problems of a compressed-time correlator are investigated from the viewpoint of signal detection. Through discussion of the LMF arid PR signals, some useful conclusions and basic formulas concerning the output signal, spectrum structure, Doppler filter set-up, noise background, SNE gain and signal envelope smoothing are obtained. As a consequence, it has been possible to design an improved sound pulse-compression receiver.
