Abstract

Abstract:

In response to the miniaturized payload application scenario of reconnaissance and jamming integrated system for unmanned platforms, a design and implementation method for a miniaturized, wideband reconnaissance and jamming integrated system based on radio frequency system on chip (RFSoC) is proposed. The paper focuses on overcoming challenges in parallel real-time large bandwidth reconnaissance and jamming techniques, as well as the construction of miniaturized, large bandwidth reconnaissance and jamming integrated software and hardware systems. In addition, improvements are made to the accuracy of angle measurement using the angle-of-arrival algorithm based on the sum-difference beamforming ratio for broadband direction finding, as well as the effectiveness of intermittent sampling relay jamming algorithm for deceptive jamming. Finally, the reconnaissance and jamming algorithms are implemented based on the software and hardware system, verifying its superior reconnaissance positioning accuracy and jamming performance.

Key words: radio frequency system on chip (RFSoC), integrate reconnaissance and jamming, miniaturiza-tion, large bandwidth
