Motion compensation techniques for coherent detection systems aboard a moving platform are discussed. Many radar and sonar systems are designed to detect moving targets within a volume of space and to reject returns from fixed objects. This can be achieved with some type of velocity (Doppler) filtering such as the moving target indicator (MTI). When the detection system is on a moving platform, both temporal and spatial processing techniques are needed to maintain good system performance. This paper presents a method for designing optimal (LMS) array correction patterns which, when used in conjunction with the primary receive pattern, minimize the effects of platform morion on the canceled clutter residue.
