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.

Detection or correction for multipath reflection

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.
