Abstract

In this letter, a method is proposed to obtain the range-Doppler map in cases of antenna–target encounter based on near-field time-domain physical optics (TDPO) method. First, the TDPO method is used to simulate the dynamic scattering echo data during the antenna–target encounter. Then, based on the electromagnetic scattering field expression, the signal processing formula for range-Doppler map simulation is derived. In this letter, modulated Gaussian pulse is used as the transmitting signal, and the corresponding signal processing method is designed, including demodulation, range compression, and slow time fast Fourier transform (FFT). This letter studies the effective combination of the electromagnetic scattering algorithm and signal processing algorithm, and proves its feasibility. The proposed method can be used to quickly generate range-Doppler map data and has significant engineering application value. Finally, some simulation examples are given to verify the feasibility and accuracy of the method.

基于时域电磁散射算法的运动目标距离-多普勒图生成框架

本文提出了一种基于近场时域物理光学（TDPO）方法获取天线目标遭遇时距离-多普勒图的方法。首先，采用TDPO方法对天线目标遭遇过程中的动态散射回波数据进行仿真。然后，基于电磁散射场表达式，推导了距离-多普勒图仿真的信号处理公式。本文采用调制高斯脉冲作为发射信号，设计了相应的信号处理方法，包括解调、范围压缩和慢时快速傅里叶变换。本文研究了电磁散射算法与信号处理算法的有效结合，并证明了其可行性。该方法可快速生成距离-多普勒图数据，具有重要的工程应用价值。最后通过仿真算例验证了该方法的可行性和准确性。

期刊介绍： IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
