Feature Extraction Related to Target Classification for a Radar Doppler Echoes

Abstract

In this paper, we consider received radar echoes data of moving ground targets and represent the corresponding signals in the time-frequency domain using spectrograms. The objective of the paper is to identify and validate the intrinsic spectrogram-based features characterizing the different classes of targets, and subsequently extract salient features for classification. We will show examples on Radar Echoes Database, containing radar echoes from various targets.
