The second-order bistatic high frequency radar cross section of ocean surface is derived for the case of a fixed receiver and a floating transmitter. The second-order radar cross section contains both the hydrodynamic contribution and the electromagnetic contribution. The second-order hydrodynamic contribution is obtained based on the first-order bistatic model with antenna motion. The derivation...
The first-order bistatic high frequency radar cross section of ocean surface is derived for the case of a fixed receiver and a floating, but tethered, transmitter. A general expression for the bistatically received first-order electric field is obtained from earlier work based on fixed antennas. A small displacement caused by the platform motion is included in the source term to modify the fixed-antenna...
This paper investigates the methodology of applying the spatial integration approach (SIA) to the scattering coefficient retrieval from GNSS-R signals for sea surface oil slick detection. The SIA has been traditionally used in the generation of simulated Delay-Doppler Maps, which emphasizes the power contribution of every sea surface point. While in this paper, the SIA is applied to the scattering...
