以成像雷达设计为背景,结合对空间目标雷达观测视角变化率的分析,给出了空间目标轨道参数和系统脉冲重复频率(PRF)的相互关系,为解决雷达回波中的Doppler频率展宽问题提供系统设计参考。目标视角变化率的分析方法是根据空间目标的轨道根数和雷达站的布站位置,通过简化模型进而分析目标相对于雷达站视角变化率与轨道参数之间的关系,并采用卫星工具包(STK)软件和数值仿真方法分别验证了该方法的有效性。仿真结果表明了本文分析方法的有效性和实用性。相关结论可为空间监视雷达系统设计及雷达资源的合理配置提供理论依据。
Based on the imaging radar design, the relationship between the spatial target orbital parameters and the system pulse repetition frequency (PRF) is given based on the analysis of the rate of change of the observational angle of the radar target in space, so as to solve the problem of Doppler frequency broadening in radar echoes System Design Reference. The method of analyzing the rate of change of the target angle of view is to analyze the relationship between the target rate of change of the target relative to the orbital parameters and the orbital parameters by simplifying the model according to the number of orbital roots of the space target and the station location of the radar station, STK) software and numerical simulation method respectively verify the effectiveness of the method. The simulation results show the effectiveness and practicability of the proposed method. The relevant conclusions can provide a theoretical basis for the design of space surveillance radar system and the rational allocation of radar resources.
