一种抑制严重非均匀杂波的机载MIMO-STAP方法
An Airborne MIMO-STAP Method for Severely Non-Homogeneous Clutter Suppression
摘要
Abstract
A two stage hytrid reduced rank STAP methodt is proposed for severely non-homogeneous enviroment in MIMO radar. It firstly suppresses the clutter and then rejects isolated interferers. In the first stage, forward/backward tempoal smoothing technique is applied to the limited secondary samples to gain more samples from which clutter covariance matrix is estimated. And then 3DT or 3CAP method is used for clutter suppressing. In the second stage, Ulon applying forward/backward temporal smoothing technique to the sample obtained from the range gate of interest,the covariance matrix of isolated interferers can be estimated. Subsequently 3DT method is also made use of to reject isolated interferers. The presented method possesses sm-nall spatial temporal aperture loss, well robustness to errors and makes good use of statistical information. Computer simulations verify its validity and robustness.关键词
