Wide frequency polarimetric radar cross section measurements
Abstract
Modern radar cross section (RCS) measurements require determination of the full polarimetric scattering matrix on complex targets. Some of the special considerations necessary for these measurements include appropriate choice of calibration targets, proper equipment setting for full target response, and effect of target support system. A polarimetric RCS measurement facility having a target support column and positioner, transmit and receive antennas, a network analyzer, and automated data measurement and analysis capability is described. The target and antennas are mounted within an anechoic chamber. The facility is presently configured for X band monostatic measurements and results are presented in the form of maps of amplitude and phase contours for a 7 cm metallic cube.
