Abstrakt: The ideal aperture current distribution of SAR antenna is discussed in theoretical sense. On the basis of the results derived by R. C. Heimiller and R. W. Bayma, the effects of current distribution which is out of phase on the synthetic array pattern and the Doppler-delay response are further analysed and numerical results calculated for the case of quadratic and cubic phase distribution are given. These results show that such phase distributions will cause a drop in gain of the synthetic array and in signal to ambiguity ratio of the Doppler-delay response. In consideration of these effects, the author proposes his additional remarks on the range of repetition frequency given by R.W. Bayma (1975). [ABSTRACT FROM AUTHOR]
