Doppler characteristics of HF backscatter - The Jindalee 'mini-radar'
Abstract
The use of the Jindalee miniradar, incorporated in the frequency management system, to deduce sea-state parameters, is reported. Estimation of the dominant wave direction, and hence surface wind direction, can be achieved by measuring the relative intensities of the two Bragg lines. The fundamental problem is to ascertain for which Doppler spectra the second-order spectrum represents a clean spectrum free from ionospheric contamination.
