Active Homing Head的用法和样例：
- Current situation and future development of semi active laser guided missiles were reviewed. Two components and the key technologies of semi active laser homing head were analysed.
- Active homing,semi-active homing,passive homing and combined homing are basic radio homing systems for missiles.
- In all systems the homing head has to remain stabilised in spece during a period when there is no guidance signal.
- Active homing guidance system mostly adopts the pulse Doppler system. Therefore, research has important significance for radar seeker simulation.
