Choice of Burst Number for Blind-Speed Avoidance

A common problem in radar system design is the choice of multiple PRF's to eliminate the blind speeds associated with coherent pulse bursts with uniform pulse spacing. This correspondence describes the procedure of selecting a set of PRF's in such a manner that the unambiguous Doppler achievable with the entire set is maximized. Based on this optimization of the set of PRF's, we determine how many PRF's the set should contain in order to minimize the required beam dwell time for a specified unambiguous Doppler.
