A scanning FMCW-radar system for the detection of fast moving objects

Abstract

This paper describes a mobile broadband 57 GHz - 64 GHz FMCW radar sensor system designed to improve the situational awareness of soldiers on peacemaking or peacekeeping missions by detecting projectiles in flight. In order to obtain an instantaneous coverage of the azimuthal field of view, a frequency-scanning meander antenna is used. Thereby, the sensors are provisioned to employ a scanning principle by radiating broadband waveforms with different frequencies into separate spatial directions.
