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.

We consider just one system in detail; an airborne, scanning sea surface surveillance radar, which operates at I-Band (9-10 GHz), is non-coherent, uses frequency agility and has pulse-to-pulse and scan-to-scan integration. The problem is that of detecting small, point sea-surface targets. Having worked through and understood this example, the reader should be well placed to carry out similar analyses of other types of radar. A few pointers towards how this may be done are given towards the end of the chapter, where results are presented of performance with a logarithmic detector; a comparison of predicted performance using the K, Weibull and lognormal distributions; and performance of Pulsed Doppler radar processing in K distributed clutter.
