摘　　要：以空气动力学为基础,根据激波传播理论,对弹丸激波传播速度的误差及斜入射时所产生的算法误差进行了建模分析,并采用了传感器三角形布局法测量斜入射角度。通过对系统误差的改进,由实验的数据得出误差分析合理,提高了弹丸脱靶量精度。Based on the aerodynamics theory and the projectile shockwave propagation theory, a mathematical modeling is constructed, the error made up of the deviation of the speed of projectile shockwave propagation and the oblique incidence are analyzed. And the angle of oblique incident using the method of sensor triangular layout is measured. Through the improvement of the system error, the accuracy of automatic target-reporting is improved based on the experimental data of the error analysis.
