Abstract

Abstract:

In order to solve the problem that the traditional space jamming countermeasure cannot deal with the mainlobe self-protecting jammings, a polarization-space joint mainlobe jamming countermeasure technique based on divided dimensions is proposed. Specifically, the digital beam of each row and column is firstly formed by using dual polarization digital receiving in multi-channel. Then, the polarization-space joint cancellation in both azimuth and elevation dimensions is carried out based on the polarization-space joint difference between the target echo and the jamming, as well as the divided dimension feature of the row and column beams. Finally, the sum and difference beams of the full array in the elevation or azimuth dimension are formed by the beams after jamming cancelling, and the monopulse angle measurement is further employed to obtain target angles. The effectiveness of the proposed technique is verified by simulations, indicating that the self-protecting jamming and multiple mainlobe following jammings can be both cancelled simultaneously with the angle measurement unchanged.

Key words: mainlobe jamming countermeasure, self-protecting jamming, following jamming, polarization-space joint cancelling, dimension-divided angle measurement
