一种多元激光探测器测高测角体制

A Kind of Multi-detecting Module Height-angle Finding System

为实现某些对地攻击弹药定高起爆以达到最佳毁伤效果,提出了一种弹载多元激光探测器测高、测角体制。该体制以窄波束脉冲激光测距为基础,通过非共面三路激光沿光轴方向测得导弹相对地面距离信息,计算导弹飞行高度及俯仰角、滚转角。采用多元Taylor公式讨论了由激光测距误差所导致的高度、俯仰角及滚转角的测量误差,结果表明其测高测角精度满足某些空面弹药的指标要求。

In order to realize some ammunition exploding at preconcerted height to achieve the optimal destructive effects, a kind of height and angle finding system was put forward based on laser multi-detecting module. This system could calculate the flying height, pitch angle and roll angle of missile with use of the un-coplanar narrow view field laser module measuring the distance between ground and missile. Multi-variable Taylor formula was applied to analyze the height-finding and angle-measurement error induced by the range-finding error. The analysis results indicate that the error meets the required standard for some air-to-surface ammunition.
