A Study on Retrodirective Cross-eye Jamming Carried by Electronic Warfare Unmanned Aerial Vehicle

Aiming at the problems of strict parameter tolerance and high interference signal ratio encountered in the practical application of airborne two source retrodirective cross-eye jamming, an innovative solution is proposed in this paper, that is, using electronic warfare unmanned aerial vehicle (EWUAV) carrying retrodirective cross-eye jamming to approach enemy guidance radar. Firstly, EWUAV retrodirective cross-eye jamming model is established in this paper. Through in-depth analysis of the model, airborne two source retrodirective cross-eye jamming model is actually a special case of it. Secondly, in determining the effectiveness of jamming, a clear indicator is set: when the explosion range of the apparent false target does not touch the physical boundary of the protected platform, the jamming is considered to have achieved the expected effect. In addition, the radar indication angle is derived in detail, and its parameters are innovatively divided into geometric and electrical parameters. Finally, through a series of simulation experiments, it is fully proved that the proposed method is not only effective, but also more relaxed and superior in parameter tolerance and interference signal ratio requirements.
