Abstract

This paper addresses the loss (if any) in radar target recognition performance if the features are extracted directly in the compressive domain compared to those extracted in the classical (Nyquist rate) domain. This study examines the impact of extracting wavelet features from compressively sampled signatures on recognition performance. Two other comparison schemes involve; 1) signal reconstruction after compressive sampling followed by wavelet decomposition, and 2) wavelet decomposition applied directly onto compressively sampled signatures using the compressive-domain equivalent discrete wavelet transform. These comparisons use real radar signatures collected in a compact range, and include various additive noise and azimuth ambiguity scenarios.
