内容简介: This state-of-the-art edition of a radar classic brings you up-to-date on new developments in clutter measurement and modeling and features a wealth of new information not found in other currently available books. Authored by a recognized expert in the field, the book covers everything from basic concepts of radar reflectivity to space-time clutter amplitude and bistatic clutter.

New radar engineers will find this to be a valuable, all-encompassing, well-illustrated survey of radar reflectivity fundamentals. Veteran engineers and systems designers will appreciate the book's new coverage of: effects of frequency agility, spatial averages for terrain, graphs from GIT clutter models, land and sea echo at extremely low grazing angles, compound statistics including the K and the Rayleigh modulated by Wiebull distributions, super sea echo events and sea spikes, bistatic land and sea clutter, and more.

资料帖就应该设置成回复可见的,要不然大家都只下载不回复了。。。。。

不过楼主设置的每个附件收一个币不算好,论坛访问很慢,这样很耽误时间的,你觉得这本书值多少币,你直接在一个附件里收完就可以了,要不然下载这本书浪费了很长时间的。。。
