摘要
本文介绍一种数字带通滤波器的设计方法。该滤波器能按给定的指标,自动完成设计任务,给出所需的幅频特性、相频特性、系统的传递函数和输出响应,并能自动给出串、并联结构形式的滤波器参数。着重讨论了此滤波器在无线电引信仿真中的应用,通过对地目标输入的仿真分析,获得满意的结果。
The paper gives a design for digital bandpass filters. The designed filter can automotically accomplish the desired task according to targets assigned. It can provide not only the required magnitude of frequency response, phase response, transfer function and output response, but also the filter's parameters in cascade or paralled form. The paper discusses also the digital filter's applications in the simulation of proximity fuzes, giving satisfactory results through simulation analyses.
