Abstract
Anti-jamming reconnaissance receivers are typically required to possess a wide instantaneous bandwidth for broad frequency coverage, high sensitivity and dynamic range, capability for detecting concurrent signals, as well as high precision in frequency measurement and resolution. To meet these demands, this paper presents a channelized receiver design incorporating a polyphase filter bank. The channelization technique partitions the full frequency spectrum into multiple sub-channels of equal bandwidth, facilitating the processing of simultaneously arriving signals and ensuring a probability of intercept approaching unity. The proposed receiver demonstrates robust efficacy in detecting various jamming signals within the operational band, including tone, comb-spectrum, and partial-band jamming, making it highly suitable for deployment in electronic warfare (EW) applications.
