This paper firstly analyzes the sources and properties of the RFI signal, and compares the characteristics of object's echo and RFI in wavelet transform domain, and then based on the different behaviors of their wavelet coefficients over many wavelet scales and the theory of multiscale decompositions, the spatially selective filtering method of RFI suppression is proposed. The performance of the method is validated on experimental data of Ground Penetrating Radar, over 88 percent of RFI is suppressed effectively by the algorithm in the experiment and little impact is made on the object's echo wave. We have compared the performance of the method to that of the notch filter in frequency domain and found it to be superior.

Because of abundant information in the signal echo of ultra-wideband ground-penetrating radar, Signature extraction becomes the key of automatic target recognition. In this paper, the wideband correlation processing is empolyed to filter and extract the typical data. The shape of target is recognized by the longitudinal and transverse typical data, and the composition of target is classificated by the power spectrum of the typical echo, and the automatic target recognition is implemented by using the RBF. The processing results of measured data indicate that the present method can effectively distinguish tube and ball, iron and aluminium.
