摘　　要：针对微功率冲激雷达引信作用范围不足而提升发射功率后,所带来的距离模糊和串扰的问题,设计了一种噪声调制的MIR系统。信噪比、距离模糊和多系统间串扰的矛盾限制了引信发射功率,通过对系统人为的加入噪声,牺牲适当的信噪比,破坏系统多倍距离间的相参性能和系统间的串扰,解决了距离模糊和系统串扰的问题,从而提高了发射功率。经实际测试验表明:MIR雷达距离拓宽至10～15m也不受多径效应和串扰的影响。The contradictions among SNR, range ambiguity and mutual interferences restrained the MIR fuze transmitting power. In this paper,a novel noise modulation module was introduced to solve the mutual interfer- ence and range ambiguity for a MIR fuze of higher transmitting power. An additional noise was put into the sys- tem at the price of reducing some SNR to break multiply range correlation, and which could solve the problem of mutual interferences, thus made higher transmitting power of MIR possible. The practical measurements showed that the MIR had a good oerformance at ranging distance of 10～15 m.
