SSR Based Monopulse Tracking System

Abstract

Secondary surveillance radar systems are predominantly used in civil air navigation. Mode A/C/S transponders – situated on the aircraft – send information to the interrogator. This represents a duplex communication, using different up- and downlink frequencies. Monopulse is a special beam-forming method, which allows us to detect the track incomprehensibly more precise than the conventional technologies. Having these technological backgrounds the aim is to develop a tracking system that detects the tracks and rotates the antenna-matrix exactly to the aircraft’s direction. This project requires antenna and high frequency signal processing design, simulation and production. Next step is to design the hardware and software of the signal-processing PCB, and the control system of the rotator. The final step of production is to test the system under proper circumstances.
