The performance of a RF(radio frequency) simulation anechoic chamber is influenced by many factors. With the geometrical optics methods, the quiet zone performance of a RF simulation anechoic chamber was analysed from the three factors, including microwave anechoic chamber layout, performance of radar absorbing materials and antenna radiation direction character. The calculating model of anechoic chambers quietness on co-polarization was gained and the quiet zone performance was computed in four frequency (0.8�iGHz, 2�iGHz, 6�iGHz, and 18�iGHz) based on reflectivity of radar absorbing materials and antenna pattern data provided by certain institute.The level layout of the quiet zone center face was gained in horizon and vertical polarization.The computed results accord with technic request, and indicate that this method could rapidly and exactly analyse the performance of a RF simulation anechoic chamber.
