Abstract
A multifunction X-band naval radar with an antenna that is mechanically scanned in azimuth and electronically scanned in both elevation and azimuth is discussed. Simulations that are mainly based on the cumulative detection probability are used to compare the performances of more or less range-ambiguous waveforms. It is demonstrated that range-ambiguous waveforms using medium pulse repetition frequencies (PRFs)-that is, with both range and Doppler ambiguities-can achieve the same cumulative detection performance as non-range-ambiguous waveforms using low PRFs mixed with the additional higher PRFs. These medium PRFs used without the help of lower ones can save time significantly.<>
