Abstract :
Adaptive waveform design for radar clutter cancellation requires knowledge of the rank of the clutter subspace. In this paper, we compare the computed clutter subspace rank, r, using three methods: (i) the exponentially embedded family (EEF) estimator, (ii) Rissanen´s minimum description length (MDL) estimator, and (iii) the statistical ranking and selection method (CWA).
