摘要
Abstract
In today's complex electromagnetic environment, the simultaneous arrival of multiple signals is inevitable, and this problem can be solved by the channelized structure based on polyphase filter banks.However,cross⁃rchannel signal problems will occur when the bandwidth of the signal is too wide,and the cross⁃rchannel signal will lose some important information.Even after channel inte⁃gration,the integrity of signal still cannot be ensured.To maintain the integrity of signals when they arrive simultaneously,an effective signal extraction method combining panoramic surveillance and filter banks is proposed.Through Matlab simulation,the correctness and effectiveness of the method are verified.关键词
