摘要

Abstract

This paper introduces the background

aim

experimental design

configuration and data processing for an airborne test flight of the HY-2 Microwave scatterometer (HSCAT). The aim was to evaluate HSCAT performance and a developed data processing algorithm for the HSCAT before launch. There were three test flights of the scatterometer

on January 15

18 and 22

2010

over the South China Sea near Lingshui

Hainan. The test flights successfully generated simultaneous airborne scatterometer normalized radar cross section (NRCS)

ASCAT wind

and ship-borne-measured wind datasets

which were used to analyze HSCAT performance. Azimuthal dependence of the NRCS relative to the wind direction was nearly cos(2w)

with NRCS minima at crosswind directions

and maxima near upwind and downwind. The NRCS also showed a small difference between upwind and downwind directions

with upwind crosssections generally larger than those downwind. The dependence of airborne scatterometer NRCS on wind direction and speed showed favorable consistency with the NASA scatterometer geophysical model function (NSCAT GMF)

indicating satisfactory HSCAT performance.
