Study on air-to-ground missile with strap-down imaging infrared seeker against moving target

In order to solve the problem that air-to-ground missile with a strap-down seeker to strike a moving target, a method to extend attacking area was present. With measurement data of carrier aircraft, quasi-body pursuit guidance was used in midcourse to create a favorable condition for terminal guidance. In terminal guidance, proportional navigation guidance law was used to strike the target accurately. The guidance information extraction method was studied, as well as the method to design a required autopilot. Based on six-freedom trajectory model, the mathematic simulation was done. The result shows that the strategy is validate and is robustness enough. It can satisfy the requirement to strike the moving target.
