In this paper we describe the main tasks of ground surveillance radars for security and perimeter protection and targets detection.Our goal is to provide a balanced and comprehensive database to enable reproducible research results in the field of classification of ground moving targets (pattern recognition).Also, in this paper, we consider received radar echoes data of ground moving targets, and corresponding signals in time -frequency domain using spectrogram and cepstrum.The database, noted as RadEch Database, containing radar echoes from various targets.The objective of the paper is to identify and validate the intrinsic features characterizing the different classes of targets, and subsequently extract salient features for classification
