多普勒谱的统计特性和熵值方式表示多普勒谱的波形特性。

-As the present study on sea clutter are shown, based on the analysis of sea clutter

Doppler spectrum characteristics, two target detection algorithms are proposed, namely,

a　Bayesian　detection　algorithm　based　on　joint　Rayleigh　distribution　and　a　feature

detection　algorithm　based　on　the　entropy　feature　extracted　from　signal’s　Doppler
