Abstract
In article the question of obtaining the radar image in pulse SAR at the multiple frequencies to a recurrence rate is considered. It allows to carry out a side visibility at the angles of demolition exceeding the maximum angles of pumping of the drive of the antenna on an azimuth.
At a side visibility the spectrum of the reflected signal from the spreading surface is concentrated about the zero frequency of Doppler, and at the pulse nature of intubation also about frequencies of the multiple to a recurrence rate.
Thus, at the expense of a stroboscopic effect does not matter at what frequency from the multiple to a recurrence rate there is a work.
The shift of the Doppler frequencies can be made by an antenna deviation on the corner corresponding to the multiple recurrence rate.
