Abstract

Aiming at the reconnaissance requirement of modern electronic warfare receiver to simultaneous signals with large bandwidth, this paper designs a broadband channelized receiver by combining analog channelization and digital channelization. Among them, the analog circuit uses multi-channel superheterodyne frequency conversion channel to convert the millimeter signal to the digital intermediate frequency band. The digital circuit integrates the functions of multi-channel ADC sampling, polyphase filtering, digital wave detection and frequency measurement into one RFSoC device, so as to realize the digital channelization. The channelized receiver has the characteristics of high sensitivity, large instantaneous bandwidth and the ability of processing simultaneous signals.
