摘要

为了提高ISAR成像雷达的距离分辨率，在每个方位仓上采用MUSIC算法和Capon MLM的时间自适应。每个方位角仓的协方差矩阵由不同载波频率制作的ISAR图像对应的方位角仓估计，以避免散射体之间的相互关联。给出了仿真结果以及一些初步的测量处理。

ISAR imaging radar with time-domain high-range resolution algorithms and array antenna

To increase the range resolution in ISAR imaging radar, time adaptations of the MUSIC algorithm and of Capon MLM are applied on each azimuth bin. The covariance matrix of each azimuth bin is estimated from the corresponding azimuth bin of ISAR images made with different carrier frequencies to avoid cross-correlation between scatterers. Simulation results are shown as well as some preliminary measurement processings.
