Multi-channel MMW-systems for short range applications

Millimeter-wave (mmW) sensorics are an interesting option for several short range applications like the imaging of persons or the monitoring of indoor environments. Due to the small antenna dimensions, compact sensor setups can be realised. This paper will discuss different setups for mmW-sensors based on the principle of a frequency-modulated continuous wave radar with respect to system architecture, calibration concepts, resulting sensor capabilities and imaging results.
