Optoelectronic Aided Polarimetric Weather Radar Signal Processing

Abstract

The paper presents the model of polarimetric weather radar with acousto-optic signal processing module. The dual-polarization FMCW radar operation is considered with range-bins processing using the two-axis acousto-optic deflector. This approach allows to greatly simplify an input analog-to-digital processing stage of the dual-polarimetric radar due to the natural properties of acousto-optic apparatus dealing with linear frequency modulated (LFM) signals.
