A measuring complex of polarimetric, combined radar-radiometers of S-, and Ku-band of frequencies for vessel and airborne application

摘要

A complex of polarimetric (dual polarization), combined active-passive devices of S (/spl sim/3 GHz), and Ku-band (/spl sim/20 GHz) of frequencies for sea surface microwave reflective and emissive characteristics simultaneous and coincident measurements is presented. The complex is dedicated to solve the problem applied to near sea surface wind and surface wave fields' parameters precise and unambiguous retrieval, as well as for sea surface signatures detection and identification. Developed systems are set on a mobile bogie moving on the height of 6.5 m along a stationary platform of 26 m of length. The measuring platform allows carry out polarimetric (vv, vh, hh, hv), multifrequency, simultaneous and coincident measurements of pool water surface microwave reflective and emissive parameters at the same or at various angles of incidence from the while of 0-60/spl deg/. This paper has an aim to attract attention of researchers interested in measurements by such kind sensors and to invite them to perform their own or joint measurements using available microwave devices and in-situ and calibration facilities.
