| Abstract: | Aiming at the problem of noise elimination of radar p icture, a way to employ wavelet packet analysis to eliminate noise of radar pict ure is proposed. By means of the wavelet packet analysis, the low frequency part and high frequency part of the superstratum can be concurrently further broken down, and therefore, more exact analysis of localities can be conducted. Based o n the above, wavelet packet analysis is improved, the problem of frequency band overlap is solved, and very good effect of noise elimination is achieved. The re sult may be received widely in application. |
