Abstract:
The backgrow nd and objective of the nit rogen launching system are proposed to test the missiles’ detachment. The tested parameters of the detachment are of ten drow ned by foreign noises. The w avelet analysis is used to disting uisk the mutation from noise, thus elim-i nat ing the noises and recognizing the trend of useful signals. The comparison betw een reconst ructed signals and theoret ical values is to show the validity of the applicat ion of wavelet analysis to the safe detachment .
