Partially adaptive radar signal processing: the cross-spectral approach

This paper is concerned with reducing the rank of the adaptive weight vector in radar array signal processing. The motivation for reducing the rank is that modern space-time processing requires many more weights than can be supported on airborne and space-segment platforms. The loss incurred in partially adaptive radar processing is that the steady-state Wiener solution of the lower rank weight vector may not perform as well as the full rank solution. Hence, this paper examines the Wiener solution of partially adaptive radar arrays and compares the performance of principal component techniques with the cross-spectral technique.
