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...
A novel technique is proposed for range alignment in inverse synthetic aperture radar(ISAR) imaging. The correlation of complex High Range Resolution Profiles of two echoes is calculated as the quality measure of range alignment, and its applicability is analyzed. The shifts introduced by the echoes are obtained in the frequency domain without interpolation, so the computation burden is greatly reduced...
