The plurality of radar-transceivers is characterized as physically spaced apart with respect to each other. The controller is in communication with the each of the radar-transceivers and is configured to coherently operate each of the radar-transceivers. The communications device communicates both a reference-clock signal and a frame-sync signal from the controller to each of the plurality of radar-transceivers whereby the plurality of radar-transceivers operate coherently. Alternatively, the system may include a reference-signal generator, a transmitter, and a plurality of receivers. The reference-signal generator generates a reference-signal characterized by a reference-frequency proportional to a fraction of a radar-frequency of a radar-signal transmitted.Type: GrantFiled: April 30, 2020Date of Patent: January 3, 2023Assignee: Aptiv Technologies LimitedInventors: James F.

Publication number: 20150070099Abstract: A system for generating a variable frequency is provided. The system includes a voltage controlled oscillator (VCO) and an integrator. The VCO is configured to output a frequency signal with a frequency value dependent on a voltage value of a control signal. The integrator is configured to vary the control signal provided to the VCO. The ramp rate of the integrator is varied so the frequency value changes at a substantially constant frequency rate over a period of time, i.e. is linearized. In one configuration, the ramp rate of the integrator is based on an input value of an input signal to the integrator determined by a digital to analog convertor (DAC).Type: ApplicationFiled: September 12, 2013Publication date: March 12, 2015Inventors: JAMES F.
