Abstract

Abstract:

According to the application requirements of reconnaissance and jamming integration in the field of electronic countermeasures and the operational requirements of wide and narrow band radar, a dual-mode reconnaissance and jamming integration architecture based on digital transceiver channelization and digital parallel up-down conversion structure is proposed in this paper. The implementation of transceiver based on 50% overlapping channel overlap without blind area is studied; and simulation model is established and its ability to reconstruct wide and narrow band signals is evaluated. On this basis, the strategy and basis of the two modes working together are obtained. Through dual-mode cooperative work, it cannot only measure the parameters of signals with different bandwidth, but also adaptively store digital radio frequency and reconstruct jamming signals with high linearity and low spurious.

Key words: electronic countermeasure, integration of reconnaissance and jamming, dual mode, digital radio frequency memory (DRFM)
