Guidance and control for missiles with a strapdown seeker

The strapdown seeker is not commonly used despite of many advantages, because of some weaknesses. This paper suggests the guidance law, the look angle control guidance, that controls the look angle measured by strapdown seeker directly. In this paper, we explain briefly the problem using proportional guidance law with the strapdown seeker and introduce the concept of suggested guidance law. And finally we verify the performance of suggested guidance law by simple simulation.
