A microwave anechoic chamber performance evaluation model was established for the requirement of anechoic chamber performance for missile guidance simulation. The model was established by geometrical optics and energy integral. Electromagnetic wave promulgating in pyramid absorber was analyzed from the principle of geometrical optics. The relation among absorber's apical angle and refracting rate, reflection frequency was educed. A method of blind zone energy integral calculation was presented. It simplifies Maxwell's equation and improves the efficiency of engineering computing. The result is more valuable than traditional methods.
