摘要
对随机二相码连续波雷达引信作了系统研究，分析了该引信波形的概率分布、平均模糊函数和脉冲压缩后距离旁瓣的概率分布，提出了一种抑制距离旁瓣至-30dB以下的统计处理方法，同时给出了系统参数的设计。分析表明，该引信具有很宽的多卜勒容限范围，能同时测定远距离和高速的目标。
The probability distribution and average ambiguity function of the fuse waveform, and the probability distribution of the range sidelobe (RSL) are systematically analysed for random binary phase coded CW radar fuses. A statistical method of reducing the RSL by 30dB is presented. In the meantime, the design of the system parameters is made. It is shown that this kind of fuses with wide Doppler tolerance can detect long-range and high-speed targets.
