摘要 舰船的姿态测量误差会影响舰载雷达对目标探测的精度,进而影响舰船的作战效能和生产能力。针对此问题,基于坐标转换分析了引入雷达探测误差的机理,建立了姿态测量误差对雷达探测精度影响的误差模型。仿真试验结果表明:雷达的测距精度与三个姿态角误差均有关;雷达的测方位角精度主要与艏摇角误差有关;雷达的测俯仰角精度与纵摇角误差和横摇角误差有关;雷达的探测精度与姿态角大小有关,且姿态角越大时探测误差越大;雷达的测距误差和测俯仰角误差与目标的方位角有关。 The ship attitude measurement errors affect the detection precision of shipboard radar on the target,further affectship’s operational effectiveness and viability. Based on the coordinate transformation,the mechanism of radar detection error is ana-lyzed to solve this problem. The error model that attitude measurement error affects the radar detection precision is established. Thesimulation experiment results indicate that radar ranging precision is related to the three attitude angle errors,the azimuth precisionof radar measurement is mostly related to the yaw angle errors,the pitching angle precision of radar measurement is associated withpitch angle errors and roll angle errors. The radar detection precision is related to the size of attitude angle,and the detection errorsare bigger when the attitude angles are bigger. The radar ranging error and the pitching angle measurement error are related to the az-imuth of the target.
