Multipoint Constraint Adaptive Monopulse Estimation in the Presence of Mainlobe Jamming
Rongfeng Li · Radar Science and Technology · 2011
The conventional adaptive beamforming leads to a serious distortion of monopulse ratio curve in the presence of mainlobe jamming,which results in a failure of angle estimation and tracking of a target.A multipoint constraint adaptive monopulse algorithm is presented in this paper.This adaptive beamforming approach is capable of suppressing mainlobe jamming while maintaining monopulse ratio undistorted,which greatly improves the performance of angle estimation.The simulation proves the validity of the proposed method.
