雷达天线伺服系统误差分析

Error Analysis of Radar Antenna Servo System

为了分析不同误差对精度的影响量值,建立了雷达天线伺服系统在2个自由度的伺服运动误差模型,并对误差源进行了分析;对不同伺服运动角度下误差对精度的影响进行了仿真和分析;仿真试验特性曲线表明:误差对精度的影响随不同伺服运动角度而变化的;可根据应用环境和实际工程指标需求,运用建立的伺服系统误差模型和仿真对误差进行控制、分配和综合,实现雷达天线高精度的外部环境感知和目标信息获取。

In order to analyzing precision influence magnitude by different errors,two degree freedom servo movement error model was set up in airborne radar antenna servo system;moreover errors of different resource were analyzed.Precision influence by error was simulated and analyzed under different servo movement angle;characteristic curve of simulation experimentation show,precision influence by error was variation along with different servo angle.According to the application environment and actual engineering index requirements,it could handle establishing servo system error model and simulation versus error controlling,distributing and synthesizing,in order to coming true radar antenna high precision by external environment apperceiving and target information obtaining.
