Abstract: A small, cheap and compact scannerless laser active imaging guided technology was proposed which can acquire the 2-D intensive imaging of targets on the ground ana the relative distance between missiles and targets timely. Based on optimal control theory and aviation mechanics, the optimal guid?ed law was deduced from taking the relative velocity into account, and the calculating methods of time- to-go were sented. The results of numeric simulation indicate that optimal guidance law has the smaller controlled energy and the shorter miss distance compared with classical proportional navigation.
