一种车载IRST控制系统的设计与仿真

Design and Simulation of a Vehicle-mounted IRST Control System

红外搜索与跟踪系统(Infrared Search and Track,IRST)探测红外特征目标,兼顾搜索目标及避免像雷达一样发出电磁波,可提高隐蔽性,同时具备跟踪红外特征目标引导打击的功能。车载IRST系统通常应用在对一定空域进行360°周扫搜索成像,实现对空域内目标搜索和跟踪功能。车载IRST的高精度定位目标位置的能力及搜索跟踪一体的工作方式,扩展了作战应用,提升了作战效能。同时,搜索启动快、调转捕获迅速及跟踪高精度等一系列指标,对车载IRST的伺服控制系统提出了高速度带宽、大加速度以及高跟踪精度的要求。

Infrared Search and Track(IRST)detects infrared characteristic targets,can search for targets and without emiting electromagnetic waves like radar,which can improve the concealment and at the same time has the function of tracking the infrared characteristic targets to guide the missiles.The vehicle-mounted IRST system is usually used for 360°circumferential scan,to search and track targets in the airspace.The onboard IRST’s high-precision ability to locate the target location and the integrated searching and tracking work methods expand operational applications and enhance operational effectiveness.At the same time,a series of indicators such as the fast search starting,High-speed search to track,and high tracking accuracy make a request for high speed bandwidth,large acceleration,and high tracking accuracy for the vehicle-mounted IRST servo control system.
