Classification: CPC B  G | IPC B  G

Claim 6:
7. An autonomous vehicle control system comprising:
(a) one or more processors; and
(b) one or more non-transitory, computer-readable media storing instructions that are executable to cause the one or more processors to perform operations comprising:
(i) obtaining first RADAR data comprising one or more first data points associated with a first angular range of an environment of an autonomous truck from a first RADAR sensor, wherein the first RADAR sensor comprises a first antenna configured to output a first RADAR beam having a first azimuthal component;
(ii) obtaining second RADAR data comprising one or more second data points associated with a second angular range of the environment of the autonomous truck from a second RADAR sensor, wherein obtaining the second RADAR data comprises sweeping a second RADAR beam over a second angular range,
wherein the second RADAR sensor comprises a second antenna configured to output the second RADAR beam having a second azimuthal component that is narrower than the first azimuthal component of the first RADAR beam, wherein the second RADAR sensor is configured to sweep the second RADAR beam over the second angular range which is closer to a rear of the autonomous truck than a front of the autonomous truck to obtain the second RADAR data, the second angular range configured to be proximate to a trailer coupled to the autonomous truck;
wherein a transmit pattern of the second antenna comprises power focused in a smaller azimuthal component than a transmit pattern of the first antenna; and
(iii) detecting one or more objects in the environment of the autonomous truck based on the first RADAR data and the second RADAR data.
