Abstract
The statistical computer simulation of measuring elevation angles of low-level targets has been carried out by means of three-frequency monopulse radar above the rough sea under multipath conditions. It is shown that the use of three-frequency monopulse radar substantially decreases errors of elevation angles measurement in comparison with single-frequency version. The use of three-frequency monopulse radar also reduces the possibility of tracking loss. The dependence of these characteristics on frequency spacing has been investigated.
KEY WORDS: monopulse radar, multifrequency radar, the low-flying target, multipath propagation, angle of elevation, computer simulation technique
