A Circuit Design for Sampling and Processing of Polarimetric Signals of Narrowband Radar

Basing on the technology of radar polarimetric signal processing, a circuit is designed to sample and process the polarimetric signals for narrowband radar. First,the principle and methods of polarimetric processing are introduced briefly. Then, according to the characteristics of polarimetric signals, the design of circuit units are introduced,such as the sample and amplitude-phase uniformity correction unit,polarimetic filter units and polarization detection unit,etc. At last, an illustration of using the circuit for virtual polarization weighting is introduced.
