3.Secondly , comparing with the algorithm that was given by english scholars a . k . nandi and e . e . azzouz in 1995 , this dissertation presents a modified automatic recognition algorithm of six kind of digital modulation types such as 2ask , 4ask , 2psk , 4psk , 2fsk and 4fsk , which only uses four key features , and has a very great exaltation in the rate of correct recognition and the performance of signal to noise , we puts forward the constitution of the best threshold which is applicable to the signal that changes within the scope of the signal to noise rate ( snr ) from 5db to 30db , and the overall success rate is not lower than 92 % when snr is over 7db
其次,针对1995年英国学者a . k . nandi和e . e . azzouz提出的针对2ask 、 4ask 、 2psk 、 4psk 、 2fsk和4fsk这六种常用的数字调制信号识别的算法,提出了一种数字信号调制方式识别算法( dmra )的改进算法。该算法仅利用四个特征参数,就可以识别这六种调制方式,而且在调制识别率和信噪比性能上都有了很大的提高,能够在信噪比不低于7db时,对实际信号的识别正确率高于92 % 。并且提出了最佳门限的设置方法,设置的门限适用于信噪比在5db ~ 30db范围内变化的信号。
4.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。
