Description

Abstract-YSCAT was an ultrawideband (2-20 GHz), near constant beam.width scatterometer intended to provide radar cross section (Ole.) measurements at varying radar and environmental parameters. YSCAT was deployed on the CCIW (Canada Centre for Inland Waters) tower on Lake Ontario for a period of six months from June to November, 1994. Using YSCAT data, this paper reports 1) observance of a "low wind-speed cutoff'', the fall-off of u o which occurs at low wind speeds, and 2) the results of fitting a Rayleigh/2-component lognormal probability distribution to the observed backscattered power measurements at C-band (5 GHz) and Xband (10 GHz). The observed characteristic trends of the fitted pdf model parameters verses wind speed and wave slope are shown. and discussed.
