Abstract

The design of reconnaissance receiver is one of the essential research of electronic countermeasures. Based on the analysis of the characteristics of the conventional receiver structure design, it puts forward a novel receiver structure, which adopts the technology of sweeping frequency in large step, 200 MHz instantaneous bandwidth and digital processing at IF (intermediate frequency). Furthermore, the key technology for implementing this receiver are discussed in this paper. This receiver owns the advantages of the channelized receiver, super-heterodyne receiver and digital receiver. It ensures the coverage of the wide bands, rapid signal interception and real-time processing of the wideband signals.
