摘要：

This paper addresses the detection of low velocity target from a shipborne HFSWR (High Frequency Surface Waves Radar). In a shipborne configuration, as a consequence of the ship motion first order of Bragg lines is spread in the useful Doppler interval where detections of ship target are expected to appear. Space time techniques like STAP, usually studied for airborne radar purposes are candidate to reduce the effect of ship motion. Influence of pitch and roll components is also discussed. Simulations of STAP techniques are given, based on a conventional architecture of processing. Estimation of the clutter covariance matrix is studied with respect of the characteristics of the radar waveform. Interleaving between the classical HFSWR waveform and a wide band learning waveform is proposed to enable the covariance estimation.
