Abstract
Based on the Lorentz reciprocity theorem, an evaluation method was proposed for the quiet zone of offset single reflector compact antenna test range (CATR) with separated transmitting-receiving feeds. Two feeds and reflector compose two separate and measured-mutually antenna systems, and there are two antenna apertures in the same quiet zone position. The electromagnetic characteristics of transmitting-receiving systems can be obtained respectively after the electromagnetic fields in the plane of two equal antenna systems were tested. The equal quiet zone fields can be obtained based on antenna acceptance theorem by transmitting-receiving antennas respective electromagnetic fields. The bistatic equal quiet zone is symmetrical and has narrower ranges, less ripple and less taper than those of monostatic. The equal quiet zone electromagnetic fields were calculated by physical optics. And this quiet zone evaluation method was verified with experiment test.
