摘要
雷达天线控制系统仿真是雷达系统目标跟踪动态仿真中一个重要环节;为解决雷达天线控制系统仿真中滞后误差大、动态效果差等问题,依据某雷达天线控制系统性能实际测试结果,以典型系统模型作为研究对象,利用频域最小二乘法完成模型参数辨识,建立系统模型,并对辨识模型进行验证;在此基础上,采用基于时域的增广矩阵法对系统进行了数字快速仿真分析;结果表明,辨识模型满足精度,且增广矩阵法能够有效快速地完成系统数字仿真,对天线控制系统建模以及快速动态仿真研究具有一定的参考价值。
Radar antenna control system simulation is considered as an important link in dynamic simulation of radar target tracking system.In order to solve the problems including large hysteresis error and poor dynamic effect and so on,according to performance test results,a typical system model is taken as the research object and its mathematical model is built by least square frequency domain identification method,then the model is validated.on this basis,augmented matrix method is proposed and simulation evaluation is used for it.Simulation and radar performance test results show that the model obtained meets precision and the radar antenna control system digital simulation is completed by the augmented matrix method effectively and quickly.It is of great reference value not only for radar antenna control system modeling,but also for the fast dynamic simulation research.
