NetRAD: Monostatic and Bistatic Sea Clutter Texture and Doppler Spectra Characterization at S-Band

Abstract

This work describes the analysis performed on coherent, simultaneously recorded, monostatic and bistatic sea clutter data. The data were generated using a networked pulsed radar system, NetRAD. This analysis is completed in both the temporal and Doppler domains, and the parameters characterised are compared between multiple bistatic angles and different polarisations. The K-distribution model is used to assess the variation in the clutter amplitude statistics between multiple bistatic data and the corresponding monostatic data. Key characteristics of the Doppler data such as the spectrum width, centre of gravity and variance of the spectral width, are evaluated as a function of bistatic angle allowing novel relationships to be defined. The results conclude that the bistatic Doppler data has a lower K-distribution shape parameter in the majority of bistatic angles compared to the simultaneous monostatic data. In addition, novel trends in the relationship between the clutter spectrum center of gravity and the clutter intensity are presented.
