Abstract
Abstract A multi-beam automobile radar system includes at least one antenna that forms a total of at least two antenna lobes. At least one of these antenna lobes serves to transmit and receive radar signals. At least one other antenna lobe serves only to receive radar signals. An advantage of the automobile radar system is that with one antenna lobe which serves only for receiving radar signals, it is possible to eliminate duplexers, for example, in the form of double rat race arrangements.

A multi-beam automobile radar system, comprising: at least one antenna including at least one feeder line and a focusing device, the at least one antenna forming first and second antenna lobes, the first antenna lobe transmitting and receiving radar signals, the second antenna lobe only receiving radar signals.
Claim 3
Dependent Claim
27 words
The system according to claim 1, wherein the at least one antenna includes only one antenna, and the first and second antenna lobes lie in a plane.
Claim 4
Dependent Claim
28 words
