雷达半物理仿真系统中的目标角度跟踪

摘要

雷达半物理仿真系统对雷达性能研究具有重要作用.在雷达半物理仿真系统中,用数字方法实现了角度跟踪.将雷达接收到的信号转换成数字信号,根据等信号法的振幅和差法,结合相位法,对数据进行分析和处理,模拟雷达的搜索跟踪过程.结果证明,用该方法实现角度跟踪满足精度要求.%The radar semi-physical simulation system is of great importance in radar research. In the radar semi-physical simulation system, angle tracking with digital methods is achieved. By turning radar echo signal to digital signal, according to the sum-difference method of amplitude ( a method of equisignal system) and the phase method, the data to simulate the searching and tracking of radar are analyzed and processed. The simulation results demonstrate the accuracy of the method.
