synthetic aperture radar with continuous waves (CW SAR)
the Markov's theory of an estimation
the radar image
Article is devoted the decision of an actual problem of synthesis of optimum system of processing of trajectory signals and is development of the quoted works of Kondratenkova G. S and Karpova O. A. for CW SAR. The model of a radar-tracking relief offered in article allows to synthesise optimum algorithm of formation of the radar-tracking image in the CW SAR and to receive an estimation of function of a radar-tracking relief by criterion of a minimum of an average square of an error. In it conditions at which application of the Bayes's approach for formation of optimum algorithms of processing of trajectory signals of the onboard CW SAR is possible are scrupulously analysed.
The received results of modelling confirm that the offered optimum algorithm of processing of radar-tracking signals allows to receive high resolution on an azimuth, realising superpermission principles (permissions of higher, than on an exit of the co-ordinated filter). The synthesised kvazioptimum filter is a basis for the subsequent operations of the automated or automatic autofocusing of radar-tracking images.
