Radar Device - A simplified explanation of the abstract

This abstract first appeared for US patent application 18450133 titled 'Radar Device

Simplified Explanation

The patent application describes a method for operating a radar device in automotive applications.

• The method involves routing antenna signals between a radar circuit and an antenna device.
• The antenna signals are routed through a common signal port of the radar circuit.
• The method includes transducing the antenna signals into radiation fields with different phase centers.
• The phase center of the second radiation field is shifted with respect to the phase center of the first radiation field.
• The method further involves constructing virtual antenna arrays using the phase centers of the radiation fields.
• The first phase center is used as the position for the first antenna, and the second phase center is used as the position for the second antenna.

Original Abstract Submitted

A method for operating an angle resolving radar device for automotive applications comprises: routing at least a first and second antenna signal between a radar circuit and an antenna device, wherein the first and second antenna signals are routed via a common signal port of the radar circuit; transducing between the first antenna signal and a first radiation field, the first radiation field having a first phase center, and between the second antenna signal and a second radiation field, the second radiation field having a second phase center, wherein a location of the second phase center is shifted with respect to a location of the first phase center; constructing at least one angle resolving virtual antenna array using the location of the first phase center as a first antenna position and the location of the second phase center of the second radiation field as a second antenna position.
