Analysis of Jammer Effectiveness in Typical Electromagnetic Combat Scenarios

This article focuses on the jamming effectiveness of jammers on radar systems in the electromagnetic combat environment. The article adopts linear frequency modulation (LFM) signal as the simulated jamming source in order to simulate the transmission of jamming signals under real operating conditions. Applying the coordinate transformation technology, the relative positions of the jammer and the radar receiver were located accurately and efficiently. Combined with the dynamic characteristics of the antenna to update the azimuth in real time, the instantaneous simulation of the signal transmission is achieved. With the simulation results as a support, this article optimises the antenna servo control system of the jamming system and automatically adjusts the antenna pointing to achieve the best jamming performance. The research results provide theoretical basis and practical guidance for the jamming strategy in electromagnetic combat, which helps to improve the real combat effectiveness of the jamming system.
