摘　　要：针对传统测量距离方向法存在舰位偏离实际舰位、射击精度下降的问题,对其进行改进。利用舰位经纬度坐标、航向和雷达测量弹着水柱距离与舷角,计算弹着水柱经纬度坐标,以舰炮发射点为坐标原点,解算弹着水柱相对提前点距离和方向偏差。仿真结果表明:改进后的方法射击精度受海况条件影响小,精度高,射程越远精度优势越明显。In order to resolve the problem that the firing accuracy o f shipborne gun descended due to the variancebetween ship actual position and calculative position, improve the measurement method. Use ship position longitude andlatitude coordinate, course and radar to measure water column distance and relative bearing, calculate the water columnlongitude and latitude coordinate. Taking the shipborne gun firing point as the coordinate origin, calculate the derivation ofwater column predicted point distance and direction. The simulation results show that firing accuracy o f the improvedmethod was more accurate and influenced rarely by sea condition, and the accuracy superiority was obvious when the firingdistance was far.
