1. A light detection and ranging (LIDAR) system for a vehicle, the LIDAR system comprising:
one or more LIDAR pixels, wherein at least one of the one or more LIDAR pixels includes:
a first optical antenna configured to emit a transmit beam having a first polarization orientation;
a second optical antenna that is offset from the first optical antenna by a particular distance, wherein the second optical antenna is configured to detect a return beam having a second polarization orientation; and
one or more receivers configured to generate one or more signals in response to detecting the second polarization orientation of the return beam.
