前言在无线电引信的研究与设计中,考查某种体制引信对目标的距离—速度特性,或比较不同体制引信的性能,以及对引信的一些重要参数进行设计,都要用到模糊函数这个概念。引信模糊函数把引信接收机输入信号的复包络描述为引信目标距离和径向速度的函数。实践证明,这个由发射波形和接收机滤波器特性所确定的函数在引信信号的分析和设计中极 Introduction In the research and design of radio fuze, the concept of ambiguity function must be used to examine the distance-speed characteristics of some kind of system fuze to the target, compare the performance of different system fuzes, and design some important parameters of fuze. Fuze ambiguity function describes the complex envelope of the input signal of the fuze receiver as a function of the fuze target distance and radial velocity. Practice has proved that this function of the emission waveform and receiver filter characteristics identified in the fuze signal analysis and design of the pole
