| Abstract: | Starting from the demand of high precision mechanism-phase scanning radar discusses, the defects of traditional antenna array plan angle measuring method are analyzed, and the principle and implementation of the algorithm of high precision IMU on array plan angle measuring function are discussed. Servo azimuth information is put forward as a measured object of IMU, for precise alignment method, to reduce the divergence speed of angle error aim to meet the requirements of the system against the array plan. And the simulation experiments the result is consistent with the requirements. |
