Radar target detection system for autonomous vehicles

Patent Number: US 10404261

ABSTRACT

A system for detecting the surrounding environment of the vehicle, comprising a RADAR unit and at least one ultra-low phase-noise frequency synthesizer, is provided.

A RADAR unit is configured for detecting the presence and characteristics of one or more objects in various directions. The RADAR unit may include a transmitter for transmitting at least one radio signal and a receiver for receiving at least one radio signal returned from one or more objects. The ultra-low phase-noise frequency synthesizer may utilize a dual loop design comprising one main PLL and one sampling PLL, where the main PLL might include a DDS or Fractional-N PLL plus a variable divider.

Radar target detection system for autonomous vehicles

FIELD

Embodiments of the present disclosure are generally related to sensors for autonomous vehicles.

(for example, Self-Driving Cars) and in particular to systems that use ultra-low phase-noise frequency synthesizers for RADAR Sensor Applications for autonomous vehicles.

BACKGROUND

Autonomous vehicles are paving the way for a new mode of transportation.

Autonomous cars require minimum or no intervention from the vehicle driver. The dynamic nature of the driving environment requires comprehensive sensing capabilities.

Therefore, autonomous vehicles are provided with various sensors to overcome and meet the challenges of the dynamic environment.
