介绍了伪码调相PD雷达引信模拟回波相位编码相关性的实现方法。利用伪随机序列的性质,采用引信发射信号调相信息同步技术,消除了模拟系统自身延迟以及信号环路中其他路径延迟的影响,实现了具有相位编码相关性的相对引信天线零距离和极近距离体目标回波的模拟。采用了调相信息预置法,实现了对任意模糊距离上地海杂波的模拟,并使任意模拟距离上的杂波保持引信发射信号的0-π调相误差特征。
This paper introduces the realization method of the correlation between phase modulation and pseudo-code phase modulation PD radar fuze analogue echo. By using the properties of pseudo-random sequences, the fuze-transmitting signal phase modulation information synchronization technique is adopted to eliminate the influence of the delay of the simulation system and other path delays in the signal loop, and to realize the zero distance and the closeness of the relative fuze antennas with phase coding correlation Distance target echo simulation. The phase information pre-setting method is adopted to simulate the sea clutter at any ambiguous distance, and the clutter at any simulated distance maintains the 0-π phase shift error characteristic of the transmitted signal.
