Attitude Measuring Technology for Short Baseline Based on Optical Collimation
HE Hongli
Abstract：As the development of micro‐manufacturing technology ,the size of radar antenna and communication antenna is becoming smaller and smaller .The relative attitude between radar antenna and the locating surface of airborne plane instal‐ling requires higher precision .How to measure the short baseline micro‐angle is becoming more and more difficult .A non‐contact optical measuring method is introduced ,which can solve the short baseline high precise attitude measuring problem . The principle ,operation method ,data processing method and precision control of the method are described in detail in the pa‐per .The method has been used in attitude measurement of small radar antenna mounted ,and gets nice effect ,which can be applied in other small surface target mounted .
