二维测试转台偏心误差修正技术研究
The Study of 2D Test Turntable Eccentricity Error Correction
摘要
Abstract
When the radar antenna is tested in the darkroom or outfield, due to the structural limitations of turntable and antenna, the electrical center of antenna will deviate from the rotation center of test turntable, which will cause measurement errors. This article uses the homogeneous coordinate transformation theory to establish a coordinate transformation model of the 2D test turntable and antenna. The coordinates of the target in the antenna can be obtained accurately, when the 2D test turntable is in any servo angle. Simulation results show that:In a 40 meters length dark room, antenna measurement accuracy can be improved at least 0.5 degrees.关键词
