Design and Measurements of MSK-LFM RadCom System

Paper i proceeding, 2021

This paper focuses on design and measurements of MSK (minimum-shift keying) LFM (linear frequency modulation) RadCom (radar communication) system which is useful in progressing industry with the advantage of cost and integration. MSK has seen many uses in communication systems and LFM in many radar applications because of its good correlation properties. This research is based on the integration of a MSK and LFM signal into a joint RadCom system. Firstly, the signal and system design are introduced, followed by methods of radar signal processing. The paper presents results from simulations and lab experiments, supporting the corresponding theory. Simulation results shows that a range resolution of 13.2 cm can be achieved using 1 GHz bandwidth. Lab measurements support this result and it is shown that a range resolution of 6 cm can be achieved using a wider bandwidth.
