Radar object detection system

1. A radar object detection system, said system comprising:
- a first sensor configured to emit a first radar signal toward a first area about a vehicle and output a first signal indicative of detected targets in the first area;
a second sensor configured to emit a second radar signal toward a second area that is different from and at least partially overlapping the first area and output a second signal indicative of detected targets in the second area; and
a controller configured to receive the first signal from the first sensor and the second signal from the second sensor, determine when a trailer is connected to the vehicle based on the first signal and the second signal, define a shadow-zone that corresponds to an intersection area defined by an intersection of a first portion of the first area obstructed by the trailer from being viewed by the first sensor and a second portion of the second area obstructed by the trailer from being viewed by the second sensor, and classify detected targets within the shadow-zone that are indicated by only one of the first signal and the second signal as false targets.

Abstract
A radar object detection system includes a first sensor and a controller. The first sensor emits a first radar signal toward a first area about a vehicle, and outputs a first signal indicative of detected targets proximate to the vehicle. The controller receives the first signal from the first sensor, determines when a trailer is connected to the vehicle based on the first signal, defines a shadow-zone that corresponds to a first portion of the first area obstructed by the trailer from being viewed by the first sensor, and ignores detected targets within the shadow-zone that are indicated by the first signal.
