光学测距传感器的工程计算

Applications of Optical Distance Measurement Sensors

由于光学测距传感器能够有效地避开敌方电磁干扰并对目标距离进行测量,因而在现代飞机上仍然得到了广泛应用。本文从光学测距传感器的工作原理及其测距的工程实现方法入手,给出了一种通过数据融合的方法对目标距离信号的采集方式进行改进的方法。改进后的方法其实际测距曲线更接近于原理曲线,与传统的折线逼近法相比,有效地减小了测距信号的误差。由于测距信号精度的提高,航空武器系统的命中精度也得到了提高,使得飞机的作战效能得以提高。

The optical distance measurement sensor can effectively escape electromagnetic interference coming from the hostile and measure the target distance, so it is still be used widely on modern aircraft. Based on the operating principle and the distance measuring approaches of optical distance measurement sensor, the method of collecting target distance signal is improved, this improved method given in the paper is based on data fusion principle. Compared with the traditional broken line method, the improved approach can effectively reduce the distance measuring error, so the probability of shots for aeronautical weapons is increased and the effectiveness of aircraft is improved also.
