摘要
提出一种应用于储频式雷达干扰机的数字射频存储(DRFM)系统设计方法.分析了综合滤波器组理论及DRFM系统的一般实现方法,利用分析综合滤波器组对信号的分解、重构能力,设计了基于分析综合滤波器组的DRFM系统.该DRFM系统保持了数字信道化接收具有的频率覆盖范围宽、动态范围大等优点,并解决了数字信道化接收时宽带跨信道信号的恢复问题.以该数字射频存储系统为核心的某储频式雷达干扰机已通过了外场测试,进一步证明了该系统的正确性.
A novel digital radio frequency memory （DRFM） system used m repeater raaar jammer was proposed. The principle of filter bank and the common structure of DRFM system were introduced. Considering the analysis and synthesis ability of filter bank, DRFM system based on filter bank was derived and designed. The proposed DRFM system has the advantages of broad band coverage and wide dynamic range. It also can realize perfectly the reconstruction of cross channel signal in channelized reception. The repeater radar jammer with DRFM system have already been tested, which proved the property of this system.
