| 摘 要： | 本文从声信号检测的观点出发分析了时间压缩相关器的有关理论问题。结合处理常用的线性调频脉冲信号及拟随机信号的情况,在相关器的输出信号及其频谱结构、多普勒滤波器组的设置、噪声背景及信噪比增益、信号包络的平滑化等方面得到了一些有用的结论和基本计算公式。改进和部分修正了已有的设计理论,为合理地设计近代声信号脉冲压缩接收机提供了依据。

| Abstract: | 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. |
