Abstract
A novel radar frontend for 77 GHz mid-range-radar (MRR) and short-range-radar (SRR) applications is presented. The radar sensor makes use of a Colpitts oscillator, frequency multipliers, and a transceive (TRX) mixer. A single sensor contains up to four channels using antenna arrays for angular detection relative to the sensor. The characterization of the integrated circuit's parameters has been carried out using a two-channel sensor with waveguide (WG) transitions. A radar measurement scenario has been realized using a four-channel sensor with a differential antenna array. All sensors have been implemented on off-the-shelf printed circuit board (PCB) substrate.
