Portable High Resolution LFM-CW Radar Sensor in Millimeter-Wave Band

This paper presents a portable radar sensor developed in the Universidad Politecnica de Madrid. The system transmits a Linear Frequency Modulated Continuous Wave (LFM-CW) with two-antenna configuration for transmission and reception. The radar transmits at millimeter-wave band with a maximum bandwidth of 2 GHz and a transmitted power of 1 W. The system is modular, compact and lightweight. The sensor allows range intervals tuning and sampling the received signals with a constant rate. By this, it is particularly attractive for portable applications. Finally, the system performance has been tested in a traffic surveillance experiment.
