针对大中口径舰炮对海射击训练时,缺少设备测量相对靶船中心的弹丸落点散布精度,提出了一种利用舰载光电跟踪仪交汇测量方法。以靶船型值为基准,利用靶船型值在屏幕上的像素尺寸,求出相对光电跟踪仪电视中心的弹着点线及偏置角,将两艘舰艇光电跟踪仪分别测量出的两条弹着点线相交,即可求出相对于靶船中心的脱靶量。给出了交会测量弹着水柱的数学模型,对测量精度进行了分析,计算结果表明脱靶量误差小于3m。
Aiming at the shooting training of large and medium caliber naval guns on the sea, the lack of equipment to measure the accuracy of the projectile falling scatter relative to the target vessel center presents a method for measuring the intersection of the shipborne photoelectric tracer. Based on the target ship type value and using the pixel size of the target ship type on the screen, the strike-point line and offset angle of the TV center relative to the electro-optical tracker are obtained, and the two bomb-point lines respectively measured by the two ship photoelectric trackers are intersected , You can find relative to the target vessel miss distance. The mathematical model of the plummeted water column is given and the measurement accuracy is analyzed. The calculation results show that the error of miss distance is less than 3m.
