引信用激光与加速度传感器复合定高技术

比较了不同类型的弹载定高体制，提出了脉冲激光与重力加速度传感器复合定高的定距原理,并对测距误差进行深入分析，得出其定高精度。对设计出的原理样机进行了实验测试，平台倾斜角度检测实验的结果表明，静态条件下最大角度误差小于0.3；0~500 m定高测试实验的结果表明，测量平均值与实际值最大误差为2.5 m，并且与目标距离无关。

Compound height determination for fuse using pulsed laser and gravity acceleration sensor

The fixed range fuse needs to complete a rapid height determination in the flight descent segment of the projectile, and then control the projectile’s action precisely. Comparing different height determination methods, this article puts forward a compound height measurement method using pulsed laser and gravity acceleration sensor, and calculates the measurement precision by deep analysis in measurement error. The prototype test on inclined platform shows that the maximum angle error is less than 0.3° under static condition; 0~500 m height determination experiments show that the maximum error between the average measured value and the actual value is ±2.5 m, which has no correlation with the target distance.
