OTHR-SW Coordinate Registration method based on sea-land transitions: Clutter model definition

In previous works we proposed a Coordinate Registration (CR) method of the received echo by pulsed, monostatic Over The Horizon Sky Wave Radar (OTHRsw). This method takes advantage from the a priori geo-morphological knowledge of the surveillance area (especially the coastline profile) and from the pronounced difference between the sea and land normalized backscattering coefficients.
