The underground transmission velocity of electromagnetic wave is the key parameter for synthetic aperture (SA) imaging algorithm of ground penetrating radar (GPR). The traditional estimation on underground electromagnetic wave transmission velocity adopts the method of measuring dielectric constant. However, this kind of method is often very inconvenient in practical application, especially when underground...
Clutter suppression is a vital problem for Ground Penetrating Radar (GPR) signal process. The clutter suppression algorithm of GPR based on Principal Component Analysis (PCA) is concerned with the good adaptability of the ground irregularity, but there is still a problem of selecting the main components which exist in the algorithm. To settle this problem, we define the principle of matrix inner product...
