Claim 0:
1. A radio detection and ranging (RADAR) sensor system for an autonomous truck, the RADAR sensor system comprising:
(a) a first RADAR sensor configured to generate first RADAR data descriptive of an environment of the autonomous truck, the first RADAR sensor comprising a first antenna configured to output a first RADAR beam having a first azimuthal component over a first angular range; and
(b) a second RADAR sensor configured to provide second RADAR data descriptive of the environment of the autonomous truck, the second RADAR sensor comprising a second antenna configured to output a 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 a second angular range 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.
