摘要

涡旋电磁波雷达回波中的线性多普勒效应和角多普勒效应可用于提取综合微运动参数。然而，涡旋电磁波雷达中旋转目标微运动参数的解析解尚未得到。针对上述问题，推导了微运动参数的解析解，并提出了一种微运动参数提取方法。首先，讨论了各种情况下的角多普勒曲线的形状和性质。然后，导出了角多普勒曲线上三个点的性质。基于这三点得到了微运动参数。仿真结果表明，该方法大大降低了计算复杂度，提高了微运动参数提取的精度。

Micro-motion parameters extraction of rotating target based on analytical solution in vortex electromagnetic wave radar

The linear Doppler effect and angular Doppler effect in vortex electromagnetic wave radar echoes can be used to extract comprehensive micro-motion parameters. However, the analytical solution of micro-motion parameters for rotating targets in vortex EM wave radar has not been obtained. To solve the above problems, the analytical solution of micro-motion parameters is derived, and a micro-motion parameter extraction method is proposed. Firstly, the shape and properties of the angular Doppler curve in various cases are discussed. Subsequently, the properties of three points on the angular Doppler curve are derived. The micro-motion parameters are obtained based on the three points. The simulations demonstrate that the proposed method can greatly reduce the computational complexity and improve the accuracy of micro-motion parameter extraction.
