This paper presents a technological demonstrator with traffic applications, which carries out three typical intelligent transportation system (ITS) tasks: traffic flow measurement, speed estimation and vehicles classification. The proposed system is a frequency-modulated continuous wave (FMCW) radar working at 24 GHz, with side-looking installation. Two signal processing modes, one-dimensional and two-dimensional, are introduced as detection scheme. Unlike other existing commercial systems, this demonstrator makes use of phase information from target echoes in order to perform clutter cancellation and target speed measurement. To this end, two different speed-estimating methods are proposed and compared by means of experimental results obtained from a complex scenario.
