Abstract

Methods and systems are provided for controlling a radar system of a vehicle. One or more transmitters are configured to transmit radar signals. A plurality of antennas or arrays are configured to operate at a common frequency and a method and system for generating random frame intervals and receiving the radar signals in response to the random frame intervals.

Description

technical field [0001] The present disclosure relates generally to vehicles, and more particularly to systems and methods for mitigating mutual interference in vehicle radar systems. Background technique [0002] Some vehicles today use radar systems. For example, some vehicles utilize radar systems to detect other vehicles, pedestrians, or other objects in their path. Radar systems may be used, for example, in implementing automatic braking systems, adaptive cruise control and evasive features, and other vehicle features. Certain vehicle radar systems, known as multiple-input multiple-output (MIMO) radar systems, have multiple transmitters and receivers. While radar systems are generally useful for such vehicle characterization, in certain situations existing radar systems may have certain limitations. [0003] In order to meet the requirements for implementation in consumer vehicles, automotive radar systems need to be high performance, low maintenance and low cost. To...
