摘要

与地面相比，平流层对逆合成孔径雷达(ISAR)系统具有更多的优势。但是平流层ISAR系统存在平台漂移问题，平台漂移给回波信号带来相位干扰。针对这一问题，首先在平流层ISAR系统中应用参数估计(PE)方法对平台漂移引起的下程相位误差进行补偿;仿真结果证明了该算法的有效性。

The quasi-stationary platform of stratospheric ISAR imaging

Compared with the ground-base, the stratosphere for inverse synthetic aperture radar (ISAR) system has more advantages. However, one problem of the Stratospheric ISAR system is platform drifting, which brings the phase interference to echo signal. Considering this problem, firstly parameter estimation (PE) method is applied in the stratosphere ISAR system to compensate for the phase error along the down-range due to the platform drifting. The effectiveness and validity of the algorithm are proved by simulation results.
