Cross Polarization Jamming and ECM Performance of Polarimetric Fusion Monopulse Radars

Abstract

The cross polarization jamming is an novel jamming technology with good effect on conventional monopulse radars. By theoretical analysis, the angular measurement error can reach the half-beam width. However, the polarimetric array fusion monopulse radars can obtain the angular measurements through two polarization arrays, work out the maximum likelihood estimation of the target angle to achieve the final angular. In this way, the radar can have its anti-jamming capability improved. In this paper, a novel model has been proposed for polarization domain countermeasures. The countermeasure performance of cross polarization jamming and polarization fusion monopulse radars has been analyzed based on computer simulation. The results show that the polarization monopulse radar is insensitive to cross polarization jamming and the jamming effect is not ideal, so it is necessary to design pertinent jamming.
