一种实时视轴跟踪的IRST系统像移补偿控制技术

针对面阵凝视器件运用到红外搜索跟踪(IRST)系统中出现的图像拖尾问题, 为解决方位搜索转台变速运动下高质量的IRST系统像移补偿, 提出一种实时视轴跟踪的IRST系统像移补偿控制技术。基于方位搜索转台速率实时感知的振镜高速、高精度控制策略, 实现了对像移的准确补偿。采用高精度M/T测速算法实现了像移的准确计算, 通过对振镜电机建立控制系统模型, 开展了振镜补偿控制算法仿真研究。实验室成像测试结果表明, 在方位搜索转台任意变速运动下, 靶标成像清晰无拖尾, 成像效果与凝视型几无差别。

Abstract

Aiming at the image smearing problem of array staring detector applied in IRST system, in order to perform image motion compensation of high quality IRST system in azimuth search turntable by variable speed motion, in this paper, presented is a kind of image motion compensation control technology using real-time LOS tracking for IRST system. High-speed and high-precision control strategy achieves accurate compensation for image motion based on real-time speed perception of the azimuth search turntable. M/T algorithm for high precision speed measurement completes accurate calculation of image motion. The scanner control system model was established, and the simulations were performed on the galvanometer control algorithm. Imaging tests performed in laboratory indicate that the target is clear without tailing in azimuth searching turntable in variable speed motion. The imaging quality is similar to that of the starring system.
