摘要

为了消除旋转相位分量(RPC)对多普勒质心跟踪(DCT)相位补偿方法性能的负面影响，提出了该方法。首先，对中频直接采样的相邻回波脉冲的相干特性进行了分析。在此基础上，提出了一种相干相位补偿方法来提高DCT的平移相位分量估计精度。与改进的DCT (MDCT)算法相比，该方法具有更好的相位补偿性能。实验结果证明了该策略的有效性和高效性。

A Novel Phase Compensation Method for ISAR Imaging in Wideband Radar

This paper is proposed to eliminate the negative influence of the Rotational Phase Component (RPC) on the performance of the Doppler Centroid Tracking (DCT) phase compensation method. Firstly, the coherent property between adjacent echo pulses sampled directly in Intermediate Frequency (IF) is analyzed in the paper. Then a coherent phase compensation method is developed to improve the Translational Phase Component (TPC) estimation accuracy of DCT. Compared to the Modified DCT (MDCT) algorithm, the proposed method achieves better phase compensation performance. Experimental results prove the effectiveness and efficiency of the proposed strategy.
