Abstract :
Based on multisensor information fusion theory and optimal control theory of structure stochastic jump system, a new guidance law is proposed for air-to-air missiles based on information fusion of active radar and infrared sensor, and its validity is testified by analysis on simulation by building digital model of missiles. Compared with proportion navigation law and extended proportion navigation law based on radar or infrared through many Monte Carlo simulations, the results show that the new guidance law reduces errors of tracking target and has smooth trajectory and small over-load, and it is important to theory and engineering application.
