This thesis documents the design and implementation of an S-band receiver for phasecomparison monopulse radar. The design and evaluation of the various sub-systems involved in realizing the receiver are discussed in detail. The designed sub-systems are connected via low loss coaxial cables to form the complete phase-comparison monopulse radar receiver. The performance of the receiver is evaluated and compared with the theoretical results, in terms of frequency response, gain and noise figure. The designed receiver is finally connected to an existing antenna system, and a preliminary test of the complete radar is performed. The initial results show that the design is successful, but the boresight-axis of the radar has shifted in angle and requires pre-comparator phase shifting in order to obtain accurate tracking. ii
