数控滤波器在引信抗干扰中应用的研究

The Study on the Application of Numerical Control Filter in Fuze Anti jamming

论述了一种以有用信号的频率变化规律控制滤波电路的频率特性来选择有用信号，抑制干扰的技术，文中给出了应用系统的原理框图，并较为详细地介绍了其中数控滤波器的设计与应用，还给出了有关的实验结果。

This paper discusses a technique for selecting useful signals and suppressing countermeasures by using frequency changing laws of useful signals to control the frequency cha racteristics of filter circuits. It gives a block diagram of the application system,and also presents the design and application of the numerical control filter in detail. Related experimental results are given in this paper.
