The application of feedback linearized guidance law in the homing guidance of the aerocraft

In the homing guidance of an aerocraft, the most important part is the precision of guidance. When the target is unmoved or moving in a constant rate, we can gain a high guidance precision by PN (proportional navigation). However, when the target move in a variable rate or in an accelerate rate or the initial aerocraft's heading is far from smash course, we cannot gain perfect guidance precision. Using feedback linear guidance law (FLGL), we can resolve such problem of guidance precision.
