摘要
为了研究舰载雷达系统误差的演化规律,分析了舰载雷达系统误差的主要来源,采用对误差传递过程进行建模的思路,推导了统一的舰载雷达系统误差计算模型。重点分析了舰艇导航信息中的姿态角误差对雷达测量目标距离、方位角和高低角的不同影响,得出雷达测距误差不受姿态角影响,方位角误差与艏向角误差呈线性关系,高低角误差受限于纵摇角与横摇角误差,并随目标方位按正弦规律变化的结论。计算机仿真结果验证了结论的正确性。
In order to study the evolution of radar system error, the main source of radar system error was analyzed. Based on the idea of modeling error transfer process, a unified model of ship-based radar system error was derived. The different impact of shipboard navigation error on the radar target distance, azimuth and elevation angles was analyzed, and the following conclusions were proposed, such as the attitude error has no impact on radar ranging, azimuth angle error and heading error of linear between high and low angle error is limited by pitching angle and roll angle error, and with the target position changes according to the conclusions of the sine law. The computer simulations testify the correctness of the conclusions.
