This letter presents a new feature extraction algorithm for ground penetrating radar (GPR) data. Our new algorithm can fully utilize the dielectric spectrum of the GPR data in different frequency bands. First, according to power spectral distribution of impulse source signal, we select the frequency band of GPR data's main energy spectrum. Second, we divide the frequency band into different subbands...
A two-stage space-time adaptive signal cancellation algorithm cascading with delay-and-sum beamforming is presented in this paper to extract signal corrupted by environmental noises. The scheme is effective to various noises and adaptive to the changes of noises environment and signal source. It also permits locating the sensors in close proximity to make the sensor array very small in size. Experiment...
