Abstract :
In this paper, we propose a modified iterative pre-whitening projection statistics (MIPPS) method for multi-target detection in non-homogeneous clutters. MIPPS determines and excludes non-homogeneous data samples by iteratively updating a pre-whitening matrix and performing the PS algorithm. Numerical results show that MIPPS improves the average detection probability of weak target when multiple targets with different signal intensities are mixed at low signal-to-clutter ratios.
