An improved pulse repetition frequency selection scheme for synthetic aperture radar
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.
