一、问题的提出我厂研制的某指挥仪,起初采用目标在弹丸飞行时间和观察时间内作等加速运动的假定,因此设置了加速度求取部件,经靶场试验结果并不理想。由于目标不能作真正的等加速运动,经过加速度求取部件后又扩大了随机误差,因此求取的加速度不是常量,波动较大,引起提前点误差扩大。因而在研制定型样机时,经过重新论证将目标运动假定取为:在弹丸飞行时间内目标作等速直线运动。但是必须考虑对俯冲目标的射击,因为俯
First, the issue put forward A plant developed by my command, initially used in the projectile flight time and observation time for such assumptions of accelerated movement, so set the acceleration to obtain components, the range test results are not satisfactory. Since the target can not be used for real acceleration, the random error is expanded after the acceleration is calculated for the part. Therefore, the calculated acceleration is not a constant and fluctuates greatly, causing the error of the early point to be enlarged. Therefore, in the development of prototyping prototype, after re-demonstration of the target motion assumptions taken as: in the projectile flight time target for constant linear motion. However, the shooting of subduction targets must be considered because of the pitching
