Abstract

Non-cooperative moving targets appear defocussed within SAR images. Moreover, in the case of ground targets, the blurring effect due to the uncompensated target motion decreases detection capabilities. In this work, clutter suppression by means of Space Doppler Adaptive Processing and ISAR imaging are combined to obtain high resolution images of non-cooperative moving targets within SAR images. Results obtained by processing a real dataset prove the effectiveness of the proposed processing chain.

基于杂波抑制和ISAR处理的运动地面目标高分辨率成像
非合作运动目标在SAR图像中出现散焦现象。此外,在地面目标的情况下,由于目标运动未补偿而产生的模糊效应降低了检测能力。本文将空间多普勒自适应处理的杂波抑制与ISAR成像相结合,获得SAR图像中非合作运动目标的高分辨率图像。实际数据集的处理结果证明了该处理链的有效性。
