解釋
假反射波-
There are two ways to enhance the radar ' s detection performance : ( 1 ) for certain signal to noise ratio, choose a optimum detection threshold, whose false decisions producing minimum cost under the preset cost rules ; ( 2 ) basically reduce the false decision probability by increasing echo ' s snr
雷達在噪聲背景中檢測信號是一個概率問題,提高雷達的檢測能力可歸結為如下兩個途徑: ( 1 )在信噪比一定的情況下,選擇一最佳門限,使其在一定風險準則下錯誤判決產生的「代價」最小。 ( 2 )提高回波信號的信噪比,從根本上減小錯誤判決的概率。 -
