Automatic targeting radar SAR raw data based on function evaluation phase error

摘要

A method for automatically focusing raw SAR data using the algorithm of range-Doppler, endonde the method is integrated in a treatment Range-Doppler of a SAR radar side view in demapa mode bands, the method comprising compression range, motion compensation and correction migraciónde scope in order to establish signals azimuthal lines to estimate spatially distributed azimuthal signals deobjetivos point, the method being characterized by the azimuthal signal of a point target is estimated from signal azimutalde a reflector consisting of several next point targets, in order to calculate the first error function phase shift Local the target point and then the error function overall phase used to correct phase signal azimuthal laslíneas prior to azimuth compression.
