摘要

本文将空间目标进动模型、宽带电磁散射计算模型以及线性调频(LFM)雷达回波信号模型相结合

提出了一种空间进动目标宽带雷达特征信号预测与高逼真度仿真的方法.利用进动目标的微波暗室测量数据

从雷达散射截面(RCS)和高分辨一维距离像时间序列两方面对模型的逼真度进行了验证

并在此基础上仿真了空间目标的动态宽带LFM雷达回波

分析了理想点散射体仿真进动目标特征信号的局限性和成对回波对雷达成像的影响.

Abstract

A high fidelity wideband radar signature prediction model for space objects with precession is developed

where the micro-motion model

electromagnetic scattering calculation and linear frequency modulated (LFM) radar signal model are integrated.The fidelity of the model is demonstrated by comparing both the radar cross section (RCS) and high-resolution range profile time sequences with anechoic chamber measured data.Wideband LFM radar returns of dynamic space object are simulated and analyzed based on the proposed model

considering the limitations of ideal point scatterers model for the precession target signature simulation and the radar imaging distortions impact of paired echoes.
