Consider the design of a minimum dwelltime set of coherent, range-unambiguous pulse bursts that will provide a specified target detection performance in a clutter-free ("clear") range interval [Rmin,Rmax]. Practical procedures are presented here for finding these optimal waveform sets versus Rmax/Rmin, subject to a peak transmit power constraint. It is always possible to design a multiple-PRF clear mode that achieves the same effective use of energy as a single-PRF waveform with a 33 percent duty ratio. Slightly higher effective duty ratios can be achieved if the radar is capable of transmitting and processing two interleaved pulse bursts at the same PRF.
