Design of side lobe cancellation and anti-jamming of unified carrier measurement and control system based on FPGA

Abstract

Direct sequence spread spectrum and spread frequency hopping technologies have certain anti-jamming performance, but their adaptability to complex electromagnetic environments needs further improvement and research. The article proposes a design and analysis of a side lobe cancellation anti-jamming system in a unified carrier measurement and control system. Its core part is designed with FPGA, so that the system has greater potential for expansion and upgrade, and the system is improved in an active anti-jamming way. Ability to work in complex electromagnetic environment.
