In order to eliminate the rock,electromagnetism field and metal field interference on the spinning missile. This paper design a set/reset cuicurt to protect the MR sensor from the jam of strong magnetic field and design a flitter circuit,rational layout to protect real signal from the jam of high frequency signal and promoted a error com-pensation and watchdog algorithm to compensate the soft/hard material error, zero error and orthogonal error. The result of rotating platform test and data analysis show that the method of antijam design combination reduce the jam error and the precision of rotation angle measure system can be improved to 1 ° . It has a certain project value for the roll angle measurement of the spinning projectile.
