Abstract
The design of Compact Antenna Test Range (CATR) is a challenging job. To achieve desired electromagnetic characteristics, choosing an appropriate algorithm for the proper design of the reflector with electrically large size is necessary. The comparison of Multilevel Fast Multipole Method (MLFMM) and Physical Optics (PO), which are the most two common algorithms used in reflector design, are performed in this paper to verify the necessity of MLFMM firstly. Then we design a novel reflector used in CATR with aperture size of 8.7m×6.9m and quiet zone size of Ф2m×2m, noting that all the design and simulation in this paper are on the basis of Boundary Element Method (BEM) module in the RainbowStudio[1].
