Radar imaging using higher order statistics
P. Niemand, Johann Wilhelm Odendaal · Microwave and Optical Technology Letters · 1997
In this article, it is proposed that fourth-order statistics are used for radar imaging rather than second-order statistics. The advantages gained using higher order statistics are demonstrated for both conventional Fourier imaging as well as for subspace-based algorithms, e.g., MUSIC. The techniques are applied to simulated data as well as data measured in a compact range. Signals that with second-order statistics would be imbedded in noise can be detected using radar imaging based on higher order statistics. © 1997 John Wiley & Sons, Inc.
