Motion compensation in radar system for autonomous vehicle

In another example, a method is provided that includes transmitting a first radar signal by a first channel of a plurality of channels of a radar unit. The method also includes receiving first radar reflections of the first radar signal by at least one reception antenna of the radar unit. Additional...

Zusammenfassung:	In another example, a method is provided that includes transmitting a first radar signal by a first channel of a plurality of channels of a radar unit. The method also includes receiving first radar reflections of the first radar signal by at least one reception antenna of the radar unit. Additionally, the method includes transmitting a second radar signal by the first channel. The method further includes receiving second radar reflections of the second radar signal by at least one reception antenna. Yet further, the method includes processing the received radar reflections from the first and second radar reflections to determine a platform movement parameter. Additionally, a virtual array may be constructed and radar signals received at common location of the virtual array may be used to determine a platform movement parameter. Moreover, the method includes operating the radar unit based on an offset determined from the platform movement parameter.
