Abstract

In this paper, the polarization error correction of dual-polarized planar scanned array weather radar in alternately transmitting and simultaneously receiving (ATSR) mode is analyzed. A method based on point correction and a method taking the complete array patterns into account are discussed. To analyze their performances, a linear error model is presented and a Monte-Carlo simulation procedure is developed. The simulation results show that, since only the information at the beam direction is used, the cross-polar measurements of point correction method degrade with the beam scanning while the second method can effectively overcome this deficiency. © 2014 European Microwave Association.
