S-BAND MONOPULSE TRACKING RADAR RECEIVER

Presenting a complete s-band receiver for a phase-comparison monopulse (PCM) tracking radar, this thesis offers a detailed design and implementation of various sub-systems used to realize the receiver. The thesis provides a comprehensive understanding of phase-comparison monopulse (PCM) radar and how any pre-comparator and post-comparator unbalances can be compensated to improve the performance of the radar. It also explains the design, implementation and measurement of several passive sub-systems (a balanced 0/180 microwave hybrid, microwave parallel-coupled-microstrip-line filters, combline filters and harmonic suppression power dividers) and active sub-systems (phased-locked frequency synthesizers, amplifiers and mixers). Besides, a system level analysis of the receiver and methods used to evaluate the performance of the receiver and radar are explained in detail.
