随机二相码调相PD引信的距离旁瓣抑制

随机二相码调相ＰＤ（脉冲多普勒）引信，是一种较为新颖的噪声调制引信体制。因距离旁瓣的存在会使该体制引信产生概率性的距离模糊，首先分析了其独特的距离旁瓣特性，然后分析了相关器组法进行距离旁瓣抑制的机理和性能，并提出了以限制码的最大游程加惯性积累电路来抑制的方法。分析表明，两者都能对距离旁瓣进行有效的抑制，而后者更适合于引信电路的特点。

RANGE SIDELOBE SUPPRESSION OF RANDOM TWO PHASE CODE PHASING PD FUZE

The random binary phase code phasing PD fuze is a novel modulated system of noise. This paper first analyzes its unique range sidelobe properties, the existence of the range sidelobe resulting in a probable range ambiguity to the fuze, secondly ,it presents theory and performance of correlator for range sidelobe suppression, and then puts forward a suppression method by max, sliding range of limiting code plus inertial accumulation circuit. The analysis indicates that both are able to effectively suppress range sidelobe, but the latter is much suited for fuze circuit.
