Motion compensation for ISAR and noise effect

A method of motion compensation for inverse synthetic aperture radar (ISAR) is proposed. The techniques of interpolation, cross correlation, and estimation are used together. Essential to the method is the fact that avoiding cross-range image aliasing due to Doppler ambiguities requires range profiles to be generated at an adequate rate. The effect of noise on motion compensation is studied by means of simulation. The quality of the reconstructed image is used to evaluate the method. >
