1. A method for selectively analyzing radar signals of a radar system of a vehicle, the method comprising the steps of:
- receiving, via a receiver, a plurality of radar signals via the radar system as the vehicle is travelling along a road;
obtaining first object data as to a plurality of objects in proximity to the road, as the vehicle is travelling along the road, from one or more first sensors of the vehicle having a first modality that is different from the radar system;
obtaining second object data as to the plurality of objects in proximity to the road, as the vehicle is travelling along the road, from one or more second sensors of the vehicle having a second modality that is different from the first modality and also different from the radar system;
for each of the plurality of objects;
identifying, via a processor, a type of the object via the one or more first sensors;
determining, via the processor, based on the type, whether the object is an object that requires tracking; and
identifying, via the processor a first angle between the vehicle and a fixed object alongside the road using the second object-level data obtained via the one or more second sensors; and
selectively analyzing, via the processor, the plurality of radar signals based upon the data from the one or more first sensors and the one or more second sensors, wherein the selective analyzing comprises, for each particular radar signal of the plurality radar signals;
determining, via the processor, a second angle from which the particular radar signal was reflected to the vehicle;
identifying, via the processor, a particular object of the plurality of objects, corresponding to the particular radar signal, based on a comparison of the second angle with each of the first angles for the plurality of objects;
selectively utilizing, via the processor, the particular radar signal for tracking, when the identified particular object corresponding to the particular radar signal has been determined to require tracking based on its type; and
selectively ignoring, via the processor, the particular radar signal for tracking, when the identified particular object corresponding to the particular radar signal has been determined to not require tracking based on its type.

Abstract
Methods and systems are provided for selectively analyzing radar signals of a radar system of a vehicle. A receiver is configured to receive a plurality of radar signals of a radar system of a vehicle. The interface is configured to obtain data from one or more sensors of the vehicle having a modality that is different from the radar system. The processor is coupled to the receiver and to the interface, and is configured to selectively analyze the plurality of radar signals based upon the data.
