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.
