Definition of Long Ocean Wave Slope for Radar Applications.
Abstract
Consideration is given to the definition of open ocean long wave slope, as a parameter for correlation with radar section (RCS). In preparation for studies of dependence of short pulse radar statistics on long wave features, we have re-examined the long time averaged RCS data previously reported by Keller, Plant and Weissman (KPW), and its dependence on in-situ measurements of long wave slope. Comparisons of RCS are made with the significant slope defined by Huang and Long, using ocean wave spectrum features; the 'radar slope' defined a KPW, using wave spectral features inferred from radar Doppler measure of orbital wave motions; and a variety of slope definitions from zero-crossing analysis of surface variance time series measured by a wave gauge. It appears that the in-situ measurements correlate with RCS better than the 'radar slope'. Possible reasons for this are discussed.
