Abstract
In pulsed synthetic aperture radar there are several constraints which restrict the selection of the pulse repetition frequency in order to obtain a good radar image. Also, it is desirable to operate the radar at larger nadir off-set angles in order to observe a wider swath-width. However, this is greatly limited by the increase in range ambiguity and nadir echo interference at large nadir off-set angles. In this paper, we propose an improved pulse repetition frequency selection scheme based on two novel ideas making it possible to operate the system at larger nadir off-set angles which is highly desirable.
