Abstract:

With the development of technology,multimode compound seeker has become the main research direction recently. But there is relative angular error in multimode compound seeker system, because of the electric axises don’t coincide with each mode,this error makes the success rate drop. In this article, an algorithm based on coordinate transformation is given to eliminate this error by make sure the deflection angle and deflection matrix. At last,the article eliminate the error successfully by this algorithm.

Key words: coordinate transformation, relative angular error, multimode compound seeker
