The synthetic aperture radar in high frequency band

The possibilities of the synthetic aperture radar construction in high frequency (HF) band  are analyzed. The fields of application of such  radar are considered

Phased antenna array with excitation adaptive to construction distortions

The dependencies of errors of phasing of antenna arrays (PAA) with spatial excitation from parameters of distortion of a hull structure surveyed are reviewed. The opportunity of build-up of algorithms of adaptation to such distortions is outlined, utilizing results of built-in system of UHF of the check of PAA, the expected results from their application rated
