摘要/Abstract

Abstract:

The principle of uniform DFT filter bank is presented. Exploiting poly-phase structure, radar jamming

system samples the intercepted wideband radar signals through analysis filter bank by different channels and linearly

modulates the intercepted radar signal according to the theory of signal and system, then synthesizes the jamming

signal through the synthesis filter bank. The method merely requires lower sample frequency, reduces the computational complexity and the data quantity to be processed. The un-ideal filter's influence to the result of signals processing is analyzed by simulating the match filter in radar jamming system.
