摘　　要：针对攻击地面固定目标的末制导炮弹,基于三自由度质点弹道模型提出了以高度y为积分自变量快速估算弹着点的方法,比较了以时间t、柱坐标角度a、高度y为积分自变量的三种估算弹着点方法的估算速度。仿真结果表明,在末制导段快速估算弹着点,三种方法的估算速度相差较大:以高度y为积分自变量的估算速度最快;以柱坐标角度a为积分自变量估算速度次之;以时间t为积分自变量估算速度最慢。提出的估算方法不但估算速度快,且估算精度亦满足工程要求。研究结果对今后该弹种的研制具有一定参考价值。About terminal guided projectiles that attack the immobile targets, the forward height integrated impact point method was presented base on 3-DOF trajectory model. The calculation rapidity of the forward time, angle and height respectively integrated impact point method were analyzed. The simulation results shown that during the terminal guided trajectory, the calculation rapidity of the three impact point estimated methods was very different. The calculation rapidity of the forward height integrated impact point method was the fastest of the three methods~ the calculation rapidity of the forward angle integrated impact point method was the second fastest and the calculation rapidity of the forward time integrated impact point method was the slowest. The calculation rapidity of the impact estimated method presented in this paper is speedy, and the estimate errors reach the requirements o~ engineering. The research results are useful for the future research of this kind terminal guided projectile.
