Abstract: A fast ramp frequency modulated continuous wave (FMCW) radar system (100) is described herein, where the fast ramp FMCW radar system is configured to employ velocity labeled multiplexing (VLM) in connection with generating detections for objects in a scene. Transmitters (110, 112) in the radar system are assigned different velocity labels that corresponds to different phase rates of change of consecutive chirps in signals emitted by the transmitters. Approaches for generating detections based upon echo signals that correspond to the emitted signals are also described herein.

Abstract: A radar system is described herein. The radar system includes a printed circuit board (PCB) that includes a metallized top layer and a substrate layer that is adjacent the metallized top layer. The substrate layer includes a substrate integrated waveguide (SIW), and the metallized layer has a slotted taper etched therein. The slotted taper is positioned relative to the SIW such that an electromagnetic signal generated by a monolithic microwave integrated circuit (MMIC) passes from the slotted taper to the SIW without an intervening microstrip line. The radar system further includes a housing that acts both to disperse heat and to suppress undesired electromagnetic radiation.

Abstract: Various technologies described herein pertain to a radar sensor system including a signal generator that generates a clock signal, start of modulation signal, and local oscillator signal. The radar sensor system includes first and second radar chips. The first radar chip synchronizes a first clock engine in frequency based on the clock signal and the first clock engine in time based on the start of the modulation signal. The first radar chip provides a first radar signal based on the local oscillator signal; the first radar signal is synchronized with the first clock engine. The second radar chip synchronizes the second clock engine in frequency based on the clock signal and the second clock engine in time based on the start of modulation signal. The second radar chip provides a second radar signal based on the local oscillator signal; the second radar signal is synchronized with the second clock engine.
