Abstract: For the simulation demands of fighter’s combat and training on IR attack-defend countermeasure, the whole attack process of multi-unit IR guided missile is simulated. A target identification algorithm based on time domain waveform characteristics is proposed, which makes the creditability of missile simulation results improved. Anti-interference technique of missile is analyzed. A missile universal motion and guidance model is established through velocity graph and practicable over-loading, which not only simplifies the operation but increases the precision. At last, the attack region of a missile under typical assault conditions is calculated. The simulation result shows that the characteristics of fast generated attack area agrees well with characteristics of real attack area.
