| 6. | 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
雷达在噪声背景中检测信号是一个概率问题，提高雷达的检测能力可归结为如下两个途径： （ 1 ）在信噪比一定的情况下，选择一最佳门限，使其在一定风险准则下错误判决产生的“代价”最小。 （ 2 ）提高回波信号的信噪比，从根本上减小错误判决的概率。 |
