Can better environmental inputs improve sea clutter estimation? A numerical experiment

Abstract

Abstract Microwave radars which are deployed near the marine environment, such as shipborne and airborne radars, are subjected to sea return or sea clutter. In many instances, sea return for radars at large angles of incidence (small grazing angles) is of special importance. Here, we examine the effects of better environmental inputs to an existing sea clutter model, which has proved to be adequate for small grazing angles, and point out the limitations in the existing model and the improvements that can be made. Furthermore, plans for improving the existing sea clutter model are outlined and discussed.
