By using the method of maneuverable missile and turbofan engine integrated analysis, a constrain and mission analysis model of anti-radiation missile and SPATR's overall performance calculation was developed and the competitive examples and the analysis were given. The mission section, the constrain conditions, the weight composition of the anti-radiation missile and the model used in SPATR were presented. Compared with anti-radiation missile with solid rocket, constrain analysis results and the mission analysis results of some anti-radiation missiles indicate that anti-radiation missiles with SPATR have supersonic flight capacity (H=11km, 2.5Ma, H=3km, 1. 8Ma), a farther missile flight range capacity (greater than 47%), hovering and standby capacity (H=3km, 0.6Ma,300s), whose performance has well application value.
