A great deal can be done to enhance and optimize the operation of a radar through careful selection of, principally, its PRFs but also of other waveform parameters. Simplifying the method of PRF selection can give a workable solution, but far superior performance can be achieved if one is prepared to take on a more complex problem entailing fine PRF resolution and combinations of PRFs with other waveform and processing parameters. The more complex problems demand more complex methods of optimization. Modern methods described here have been used with great success in the design of radar waveforms supporting a wide range of modes such as high and medium PRF pulse Doppler and ground-moving target indication (GMTI) and applications such as airborne fire control and long-range early warning radars.
