摘　　要：炮兵指挥车通过方位引出装置实现对目标方向和位置的测量。采用两环结构的方位引出装置存在着框架误差,影响对目标位置和方位角的测量精度。通过应用方向余弦矩阵法,研究了框架误差的产生机理,推导了框架误差的补偿公式。通过数学分析和仿真,验证了方位引出框架误差补偿的正确性。实验结果证明:该补偿方案能够对方位引出两环结构带来的框架误差进行实时修正,补偿后的精度(PE)≤0.3 mil,满足战技指标要求,实现对目标位置和方位角的准确测量。Artillery command vehicle realizes the measurement of the aim's bearing and position by using a device to extract azimuth. The azimuth extractor with two-ring structure has gimbal error, which would influence the aim's measurement precision. The generation mechanism of gimbal error was studied and the error's compensation formula was derived by applying the direction cosine matrix method. The mathematical analysis and simulations verify the correctness of the compensation for the gimbal error of azimuth extractor. The experiment shows that this method could implement real-time correction for the gimbal error, and the precision after compensation is ≤0.3 mil, meeting the requirements for the tactical and technical index and realizing the accurate measurement about the aim's bearing and position.
