低空监视系统中雷达引导光学跟踪仪的数据融合设计与实现

Design and Implementation of the Radar Guiding Opto-Electronic Tracker Data Fusion in the Low-altitude Surveillance Systems

为了使低空监视系统能全天候、全天时有效地工作,克服了单一传感器的不确定性和局限性,将警戒雷达与光电传感器配合使用,警戒雷达波束较宽,具有较强的空域搜索能力,能够及时发现来袭目标,而光电传感器测量精度比警戒雷达高,但目标搜索能力较弱,雷达引导光电传感器是一种基本的协调使用方式。雷达引导光电传感器是指通过雷达锁定目标并引导光电传感器伺服转台转向目标,通过和雷达观测数据融合在雷达界面显示光学跟踪仪器目标信息。

In order to make the people defense surveillance system work all weather and round the clock effectively, can overcome the uncertainties and/imitations of single sensor. The radar should be coordinated with the Opto-Electronic Tracker. Surveillance Radar have global searching capability which it beam width.,and find the threatening targets in time. Opto-Electronic Tracker measurement accuracy the extended Surveillance Radar, but target searching capability weak, Radar guidance is a basic coordinat ion method, which leads the servo to veer to the locked target o fthe radar. Through Opto-Electronic Tracker and radar data fusion display target information.
