Abstract: The radar application for projectiles’ or rockets’ speed measuring invokes needs for obtaining a larger number of flight parameters in addition to the starting and ending speed. Modern radar projectile trajectory tracking systems can provide such data, however, they are very expensive and bulky equipment. This paper presents a design principle for projectile tracking radars with four printed microstrip antennas, over the spatial angle. The presented radar has small dimensions and belongs to the low cost category suitable for various types of field testing. The described solution of monopulse radar operates in a frequency range from 10.3 to 10.7 GHz; however, the same concept could be applied to other frequency bands.

Key words: angle measurement, muzzle velocity measurements, radar beam, patch antenna
