Abstract

Micro-motion information from very high-resolution SAR imagery has the potential to provide additional insights in support of advanced target detection and recognition. Due to the implicit assumption in the imaging process that a scene is stationary, target motions and micro-motions result in residual phase shifts and modulations that can be retrieved to obtain kinematic characteristics. In this paper, an approach exploiting sub-aperture processing and phase analysis is introduced to analyse micro-motions of both land and maritime targets. The effectiveness of the proposed approach is demonstrated on real SAR data and validated using ground truth measurements.
