摘要
雷达天线在测试或者使用中,由于天线装在转台上,它的电气中心不可能与转台坐标系的原点重合,转台坐标值与天线坐标值不相等。本文给出了天线与转台之间的坐标关系,在天线的精确测量中,可以依据此关系把测试所得的转台坐标值变换为天线坐标值,同样在雷达应用中,也可以把已知的天线波束坐标值变换到转台(伺服)坐标值。
When radar antenna is in operating or under test, electric center of the antenna can not be coincident with origin of coordinate system of the turntable because the antenna is mounted on the turntable. Coordinate relation between antenna and turntable is provided in the paper, it can be used to convert measured coordinates of the turntable to coordinates of the antenna during test; conversely, it can also convert known coordinates of antenna beam to coordinates of the turntable（servo）during radar operating.
