摘要
The present invention relates to a method for generating a long-distance inverse synthetic aperture radar images using a polynomial and Gaussian functions and devices relates to. According to the present invention, there is provided a method for generating a synthetic aperture radar imaging station to the target are flying, is scattered from the target and then receiving the reflected wave which is reflected, by using the side distance from the reflected wave extraction to generate an estimate of the target locus phase, phase trajectory estimation to model a Gaussian function by a polynomial and the combined orbital, obtaining a locus of the center of gravity away side view, the error between the estimated trajectory and the center of gravity trajectory set parameter values to configure the orbital to minimize a step, step a cost function of the distance away side view arranged to adjust the parameter value to be the maximum, and compensating the phase error of the distance away side view, aligned, and using the distance to produce a reverse side synthetic aperture radar image includes. With respect to a polynomial function and a Gaussian function orbit combined according to the present invention in this way, the difference between the center of gravity and trajectory estimation model primarily to minimize and, by modeling and secondarily through the PSO algorithm, a more accurate and finer may perform the alignment distance.
