Abstract

We use a six-port reflectometer for microwave diversity imaging measurement in a compact range arrangement and develop the associated calibration method. In the calibration, a reference scattering object is placed at the object positioner with the use of a calibration circuit. Microwave diversity imaging experiments are conducted for three types of scattering objects, a metallic cylinder, four distributed line scatterers and a scaled B-52 aircraft model. The operation frequency is from 8 GHz to 12 GHz.
