Sea Clutter: Scattering, the K Distribution and Radar Performance — Recommend this title to your library

Thank you

Your recommendation has been sent to your librarian.

One of the ultimate aims of modelling sea clutter is to inform the development of improved radar systems that meet the operational needs of their users. However, the translation from a user's requirements to the entry into service of an equipment that meets these needs in an acceptable way is a very complex process. From the viewpoint of a radar designer, an important part of the process is the methodology for specifying and measuring radar detection performance. This methodology is the subject of this chapter, with emphasis being placed on the issues relating to maritime radars and the detection of targets in sea clutter.
