摘要

针对空间目标平移运动引起的微多普勒频率会增加，给微多普勒特征提取带来困难的问题，提出一种基于经验模型分解(EMD)实现精确平移运动补偿的新方法。分析了空间目标轨迹运动对微多普勒特征提取的影响。实现了回波的轨迹运动补偿，提取了微多普勒特征。仿真结果验证了该算法的有效性。

A new method of translational compensation for space spinning target based on EMD

As the micro-Doppler frequency will be added to the Doppler frequency caused by space target translational movement, which brings difficulty to the micro-Doppler characters extraction, a new method to realize accurate translational movement compensation based on empirical model decomposition (EMD) is proposed. The effect on micro-Doppler feature extraction induced by space object trajectory movement is analyzed. The trajectory motion compensation of echoes is realized and the micro-Doppler feature is extracted. Simulations are given to validate the effectiveness of the proposed algorithm.
