The first- and second-order monostatic cross sections of swell contaminated seas for high-frequency ground wave pulsed radar operation are derived based on the fundamental electric field equations. The ocean surface, a mixture of both swell and wind wave components, is first represented with a Fourier series. The corresponding equations of the received electric field are then obtained. Fourier transformation...
Based on the previously developed monostatic HF radar cross section model for swell contaminated seas, a new inversion algorithm for swell information from radar sea echoes is proposed. The received electric field time series with external white Gaussian noise is first simulated, from which the Doppler spectrum is obtained as a periodogram. Next, all swell peaks in the spectrum are identified and...
Based on HF bistatic models for the first- and second-order ocean cross sections developed earlier, a new monostatic cross section model for swell contaminated seas is proposed. The methodology of modelling is to incorporate a Wallop wave spectrum to represent the swell portion while describing the wind wave part with a typical Pierson-Moskowitz spectrum. Then, it is assumed that the total ocean surface...
