Abstract: Ranging and detection data is processed to identify or correct for multipath reflection. A sensor point that represents a location of an object, the location based on an incidence of an electromagnetic wave received at a sensor is obtained. The first sensor point is determined to be a product of multipath reflection. A first point of reflection on a surface of a surface model is determined. The location of the first sensor point is corrected based on the first point of reflection on the surface of the surface model.

Abstract: A radio detection and ranging (RADAR) sensor system for vehicles, such as autonomous vehicles, includes a first RADAR sensor configured to provide first RADAR data descriptive of an environment of a vehicle having a first antenna configured to output a first RADAR beam having a first azimuthal component over a first angular range and a second RADAR sensor configured to provide second RADAR data descriptive of the environment of the vehicle, the second RADAR sensor having a second antenna configured to output a second RADAR beam having a second azimuthal component that is narrower than the first azimuthal component of the first RADAR beam, wherein the second RADAR sensor is configured to sweep the second RADAR beam over a second angular range closer to a rear of the vehicle than a front of the vehicle to obtain the second RADAR data.
