  • A fully 3-D image-reconstruction algorithm that quasi-monostatic mode is used and the transmitting antenna works in step frequency was developed.The algorithm is not restricted by far field as the traditional imaging algorithm. Through synthetic aperture processing for radar data, the resolutions of the image and the detecting ability of radar are improved .A new Stolt interpolation method , which can increase accuracy of interpolation and reduce computation time, was presented. 3-D image of the objects can be achieved through the fast Fourier transform after interpolation. Numerous imaging results from simulations and experiment were presented. These results show that the algorithm for 3-D image-reconstruction based on this interpolation method can produce a microwave 3-D image with high resolutions.
