A NEW HYBRID METHOD OF CALIBRATION FOR POLARIMETRIC RADAR CROSS-SECTION MEASUREMENTS

The main problem in polarimetric measurement is to retrieve all the properties (phase and magnitude) of the scattering matrix of the studied object. In most cases the proposed techniques [1-3] are very complicated and are not adaptable to intensive applications, as in the industrial domain. The development of an original technique is proposed here. The technique is very efficient and simple to use. It is based on a modification of an existing technique developed in Reference [1]. The main advantages are the facility of placement of the targets and the fact that there is no need to know the distances between the calibration targets and the emission/reception system.
