Land sea clutter from FM based passive bistatic radars

This paper examines ground and sea clutter from three different FM-based Passive Bistatic Radars (PBRs). Measurement data has been obtained for low grazing angles. The PBRs used to collect the displayed data, with all their relevant parameters, are defined and clutter analysis procedures are described. This work, based on measured data, yields valuable insight into the nature of VHF bistatic clutter.
