Abstract
A radar system for motor vehicles, having a least one radar sensor having a range of less than 50 m for monitoring traffic in an adjacent lane, wherein the radar sensor has a phase-controlled antenna and a control device for setting a plurality of radar lobes having different geometries.
Claims11
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.
