Abstract
A Doppler radar sensor platform suitable for measurements of vibration and velocity of any objects is described here. The platform consists of several multipurpose transceivers operating at two different millimeter(mm)-wave frequency bands. Silicon-Germanium BiCMOS technology enables the implementation of the multiband transceivers very cost-effectively in the mm-wave frequency region, which offers an extremely high potential for the performance improvement and the miniaturization of the sensor platform. The radar transceivers are equipped with binary-phase shift-keying modulators as well as I/Q receivers and can be utilized with the pseudo-random noise radar modulation technique to allow distant-selective Doppler measurements. This technique not only allows specific targets to be selectively measured while suppressing the noise from the environment, it can also be used to determine the location of the specific targets. The transceivers can be cascaded for the implementation of a MIMO radar system to allow digital beamforming operation of the radar. Radar measurements were performed with the implemented MIMO radar system to determine the vibration frequency and the location of vibrating objects in the anechoic chamber for demonstration purposes.
