半实物仿真中的高精度激光回波模拟技术

过去寻的探测系统只获得目标的二维信息:俯仰角度信息和偏航角度信息。在战场环境日益复杂的今天，目标和导弹的速度都越来越快，飞行控制的时间也越来越短。由于这些变化，过去的探测系统的能力渐渐不能满足现代作战需求。随着应用需求的不断扩展，需要在制导过程中能够获得更加丰富的目标位置信息，不仅是方位角度信息，还应包括距离信息。于是，激光测距技术成为制导领域的一个研究热点。针对激光测距系统的测距功能和测角功能研制了一套回波模拟系统，称之为激光回波模拟器。对验证激光测距系统性能的半实物仿真系统进行了系统设计，并实验验证了这套系统的可行性。

Technology of simulation for high-precision echo laser

Along with the expansion of application demand,the new generation of guiding system must be able to obtain rich information in the detection process,including angle and distance information.Therefore,laser ranging technology becomes a hot spot in the field of guiding field.In order to provide the simulation experimental conditions for laser ranging technology,a lot of works on laser echo simulation were done.In this paper,the development of the echo simulation system was described,which had the characteristic of angle and distance measurement for the laser ranging system.This system was named as laser echo simulator.The simulator could give the proper echo signal with a corresponding delay after receiving the trigger signal from the detection system.The echo characteristic and delay control capacity were analyzed.The hardware-in-the-loop system design was presented to verify the performance of laser ranging system.The experimental results indicate the feasibility of the system.
