Abstract. Development, construction and testing of a stu- dent laboratory model of the radar system that can be used for monopulse tracking is described. The laboratory model is simple and can be assembled from the existing equip- ment while the missing parts can be manufactured in a basically equipped RF electronics
the target echo. It is the preferred tracking technique when accurate angle measurements are required. The monopulse angle method may be used in a tracking radar to develop an angle error signal in two orthogonal angle coordinates that mechanically drive the boresight of the tracking antenna using a closed-loop servo

Monopulse tracking radars can employ both antenna reflectors as well as phased array antennas. Fig. 11.7 show a typical monopulse antenna pattern. The four beams A, B, C, and D represent the four conical scan beam positions. Four feeds, mainly horns, are used to produce the monopulse antenna pattern. Amplitude.

Figure 3: estimating of the angular position in older radars (not using a monopulse method). Monopulse radars find their origin in tracking systems. Since the late 1970s, the principle of monopulse has been adapted to suit PSR and SSR systems and is in common operational use world-wide today. A target will be seen by a
Monopulse radar is a radar system that compares the received signal from a single radar pulse against itself in order to compare the signal as seen in multiple directions, polarizations, or other differences. The most common form is an adaptation of conical scanning radar which compares the return from two directions to
