摘要
Abstract
In traditional space-time adaptive processing (STAP) radars,angle and Doppler parameters are coupled with the adaptive sum and difference technique.Moreover,the parameter estimation performance degrades dramatically if the target signal is included in the training support.In this paper,we propose a novel static sum-and-difference beams matched STAP method.In our approach,the constraint is designed by incorporating both the magnitude and phase responses.The adapted beampattern is forced to be close to that of the static sum-and-difference beams in magnitude and phase response,and thus the mainbeam of the adaptive sum-and-difference beams is well maintained.As a result,the target cancelation due to the presence of the desired target in the training support can be alleviated.The angle and Doppler parameters are decoupled since the static sum-and-difference beams are independent in angle and Doppler domains.Simulation examples are presented to demonstrate the effectiveness of the proposed method.关键词
