摘要
基于室外消光比方法,完成了机载多脉冲激光雷达性能综合测试系统的研制;该系统由测控软件、便携式检测仪、能量计和光学设备等组成;测试软件基于Visual C++开发,采用串口通信技术和多线程技术,使系统具有较好的稳定性和可靠性;采用自动控制转盘式光阑的方法,提高了系统的实用性;试验结果表明:所研制的系统可实现对多脉冲激光雷达多个主要性能参数的精确测试,有利于激光雷达性能综合测试的自动化,为产品的批量生产提供有效的检测手段。
Based on principle of extinction ratio outdoors, automatic test system of Airborne Multiple Impulse Laser Radar Maximum Range was developed, which consists of control software, energy meter, portable detector, optical equipment. Multi-- threading technology, serial communication technology and modular programming ideas are used in the development of controI software based on Visual C＋＋, which make system has better stability and reliability. Rotary diaphragm was used in the beam divergence angle test, and which make system more practical. The test results show that ： the system can realize the accurate testing of multi pulse laser radar multi key performance param- eters, is helpful for the automatic test of laser radar, provides the effective method for the production of products.
