MUSIC-algorithm based on adaptive threshold of part amelioration and extract
2009
Using the proper threshold will extract the minimum eigenvalue correctly.Besides,it must have self-motion to the gate limit when it could adapt to signal-to-noise ratio of large area and fast snap rate. Usually,signal-to-noise ratio has more influence on the gate limit than fast snap rate does.There exists a gate-limit formula after a lot of experiments,and it is(15(SNR) ^0.8*(snap)^0.2).The SNR means signal-to-noise ratio and snap means the rate of taking a photograph.After taking repetitious experiments, it shows this gate-limit formula has good adaptive ability,which could adapt to various SNR and change of fast snap rate,also exactly estimate the signal source.
