Detection in the maritime domain requires the radar return from an object of interest (target) to be distinguishable from the background interference (sea clutter and noise). These radars traditionally use non-coherent processing methods due to the time-varying and range-varying nature of the Doppler spectra. However, the radar backscatter may contain sea-spikes which can last for seconds and resemble targets. In this paper, a method of sparse signal separation known as 'basis pursuit denoising' has been applied to two different sea clutter data sets to demonstrate the potential for improved detection performance. We also explore how the parameters required for this technique can be selected depending on the target velocity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
