摘要
激光引信在弹道导弹上被用于测量并控制弹头的爆炸高度。为研究激光引信的测距性能,在给定引信的测量高度指标后,基于脉冲激光测距方程及雪崩光电二极管输出信噪比计算公式,仿真得到了在不同探测器接收口径及不同大气能见度条件下,激光引信接收信噪比随激光器峰值功率变化曲线,确定了满足一定虚警概率和发现概率条件下所需激光器的最小峰值功率值,并分析了接收口径及大气能见度对激光引信测距性能的影响。
Laser fuzes are used to measure and control the blasting height of ballistic missile's warheads. To research the ranging performance of laser fuzes, suppose the blasting height is given, based on pulses ranging equation and the output SNR formula of avalanche photodiodes, the relation of SNR of detectors and peak power of laser is calculated and simulated under varying receive aperture of detectors and atmospheric visibility. Then the lowest peak power can be determined on condition that false alarm probability and detection probability of laser fuzes must satisfy the tactical requirement. Furthermore, the influence of receive aperture and atmospheric visibility on laser fuzes is analyzed.
