Radar system for motor vehicles
First Claim
Patent Images
1. A radar system for a motor vehicle, comprising:
- a control device; and
a radar sensor to monitor an area surrounding the motor vehicle without the presence of another radar sensor monitoring the same area, the sensor configured to monitor traffic in a lane adjacent to the motor vehicle, the radar sensor including a phase-controlled antenna and the control device configured to set a plurality of radar lobes having differing geometries, the control device being further configured to generate different configurations of radar lobes in succession over time by changing at least one of a total number of radar lobes being generated at a particular time and a geometry of the plurality of radar lobes, the change occurring during vehicle operation;
wherein the control device analyzes propagation times, frequencies and phases of a radar echo to determine direction from which the echo was received and distinguish which one of the plurality of radar lobes the echo originated from.
