International audienceThe GO-SSA-Extended model is an extension of the physical GO-SSA model with augmented range of validity. It is obtained through the addition of extra empirical terms. This improved model can predict the backscatter reflectivity from the sea surface for the full range of grazing and azimuthal angles. This model compares favorably with Xband experimental measurements (VV and HH polarization) acquired by the ONERA and DSTO

“…Fig. 2 shows an example of the variation of σ u 0 with grazing angle, looking upwind, for VV and HH polarizations, using the parameters from Table III. The Ingara trials data has been used by the DSTO Imaging Radar Systems Group (IRSG) to develop models [18] based on fitting a large amount of data covering 360° in azimuth and for grazing angles in the range 15° to 45°. There were 12 days with slightly different wind speeds.…”

This paper reviews the published literature on the characteristics of mono-static radar sea-clutter observed with high grazing angles (typically above about 10°). To date, most of the analysis and modelling of sea-clutter has been undertaken at low grazing angles with the main application being for surface and airborne maritime radars. The paper identifies some of the data sets that have been collected and the empirical models that have been developed from them for the normalised radar crosssection. The amplitude statistics and Doppler spectra of high grazing angle clutter are reviewed and the implications for radar design and target detection are discussed.

“…This data has been used to evaluate a series of empirical models of the observed sea phenomenology. These include the mean radar backscatter, the amplitude distribution and the Doppler spectrum [6]- [8]. Recently, a study using these models has looked at target detection performance between K and KK distributed sea-clutter [9].…”

The effect of temporal correlation with K and KK-distributed sea-clutter

Sea-clutter has been studied for many years over a range of sea conditions, polarisations and geometries. The Defence Science and Technology Organisation's (DSTO) Ingara airborne X-band fully polarimetric radar has been used to collect data in the medium grazing angle region to evaluate models of the observed sea phenomenology and determine their impact on target detection. The focus of this work is the temporal correlation that may be present in either the target and / or clutter components of the received pulses. If this correlation is not accounted for in a radar model, the required signal to interference ratio (SIR) for a given probability of detection (Pd) will be incorrect by several dB, resulting in over-estimated performance. This paper describes a model for the temporal correlation of medium grazing angle X-band sea-clutter and quantifies the detection performance for Rayleigh fluctuating targets with both K and KK distributed sea-clutter.
