多传感器、光电结合的某自动对准系统设计

Auto-alignment system with electronics & optical equipments

设计了一套完成照射器检测天线对照射器的自动对准过程的系统。系统以电对准和光学对准两种手段相结合的方法,利用多传感器技术、GPS定位及测姿技术、无线数据传输以及多通道实时视频采集技术完成了系统设计。系统中,以GPS接收机分别测量检测设备和被测照射器的GPS坐标,通过计算得到两者的相对航向,利用测姿设备完成两者的姿态测量,得到相对俯仰角,从而完成检测天线对照射器在航向和俯仰两个方向上的初步对准。之后,利用光学对准系统对被测照射器电磁波的最大功率方向进行精确对准。利用Lab Windows/CVI 6.0和EVC完成了软件设计。实验结果表明系统满足设计指标要求,具有良好的应用前景。

An auto-alignment system from the test aerial to the irradiator is designed. Based on the technologies of multi-sensors, GPS positioning ＆ attitude, radio data transmitter and multi-channel real-time video acquisition, this system combined the electro-alignment and the optical alignment. First, in the subsystem of electro-alignment, the GPS receiver measure the attitude of irradiator and the test equipments, through a serious of calculation, the headings angle between this two is worked out, the attitude measuring equipments are used to get the pitch angle, thus the first alignment from test aerial to the irradiator is finished. Second, use the optical sub-system to align to the maximum power direction precisely. And the software is developed with Lab Windows/CVI 6. 0 and EVC. Results show that this system meets the engineering need.
