Height measurement technology and system for the signal flare based on the characteristics of sound and light

针对现有信号弹高度测量方法测量方案复杂,对操作人员在技术方面的要求较高,实验设备价格也比较昂贵等问题,提出基于声光特性的信号弹高度测量方法。该方法利用信号弹发射产生的声、光信号在空气中传播速度相差较大的特性。可根据信号弹在最高点处声光到达传感器的时间差进行测量。实验和仿真表明:它的操作简单,成本低廉,运行稳定,性能可靠,适用于信号弹高度的测量。

Existing height measurement methods for signal flare has complex scheme,high demand to operating personnel and the experiment equipment.The thesis puts forward a measurement method for flare height based on the sound and light characteristics,this main uses the large difference characteristics of sound and light velocity in the air producing by launched flare.Using sound velocity in the air multiplied by propagation timing difference between sound and light can calculate signal flare launch altitude.The experiment and simulation results show that the operation is simple,has low cost,the operation is stable,reliable performance,applicable to flare the measurement of height.
