A Unified Radar Alignment Model with Error Analysis for Shipboard Combat System

针对舰艇作战系统对准工程的需要,根据坐标变换原理推导了一种统一的舰载雷达探测角度和探测距离的对准计算模型。分析了对准过程中舰艇姿态变化以及仪器测量误差等动态不确定因素对作战系统对准精度的影响,并基于误差理论推导了雷达探测角度和探测距离对准理论真值的最大绝对误差计算公式。根据上述模型计算舰载雷达对准的理论真值及其最大绝对误差,可以为舰艇作战系统对准精度分析提供辅助依据。Matlab数值仿真结果验证了本文方法的有效性。

Based on coordinate transformation theory, a unified computation model was proposed for shipboard radar s alignment of detection angle and distance. The model well meeted the requirements for the calibration engineering of shipboard combat system. The influences of ship attitude variation and instrument measure errors on combat system s theoretical calibration values were analyzed. On the basis of the error theory, the model also developed a set of equations to determine the maximum absolute errors of theoretical alignment values of the radar. With the above alignment computation, the model is can assist the calibration in the precision analysis of shipboard combat system. Matlab data simulation results demonstrate the calibration model＇s effectiveness.
