Aimed at the difficulties of real-time attitude determination measuring of ship-based radar in the navy range and the problem that the real-time coordinates of the radar antenna center is difficult to measure accurately, a radar measuring information correction method is put forward according to the sup- port capabilities, equipment layout and participation situations. The method combinated vehicle attitudes real-time measurement and measuring positions real-time correcting based on multi-antenna GPS and the radar zero error dynamic correction. The detailed radar measuring information correction method, model and process are given. And the correction errors are analyzed. Practical application and test results prove that the method can realize a high accuracy of the real time measurement of radar antenna center coordi- nates and radar measuring attitude correction at a low cost. The problem of real-time attitude measuring and position correcting of the ship-based measuring radar can be effectively solved.
