|
摘要
图像自寻的火箭弹目标命中概率直接影响其作战使用。针对该火箭弹弹道及探测设备特点,在分析火箭弹落点偏差产生过程的基础上,通过建立末段弹道简化模型,计算分析了空气阻力及重力、风速风向对落点偏差的影响;然后构建了基于导引盲距与跟踪角误差影响的落点偏差数学模型与命中概率计算模型,并仿真分析了各因素的影响规律;最后根据图像自寻的火箭弹导引盲距推算了跟踪角误差指标要求,并仿真了其落弹散布情况,为该弹种研发与使用提供了重要参考。
The target hit probability of the image homing rocket has a direct impact on its combat use. In view of the characteristics of the rocket trajectory and detection equipment, based on the analysis of the formation process of the landing point deviation of the rocket, a simplified model of the terminal trajectory was established, with the effects of air resistance, gravity, wind speed and direction on the landing point deviation calculated and analyzed. Then, the mathematical model of landing point deviation and hit probability calculation model based on the influence of guide blind distance and tracking angle error were constructed, with the influence rules of each factor simulated and analyzed. Finally, according to the blind distance of image homing rocket missile guide, the tracking angle error index requirements were calculated, with the dispersion of projectiles simulated, which provides an important reference for the development and use of the missile.
