1. A light detection and ranging (LIDAR) sensor system for a vehicle, comprising:
a first transmitter configured to output a first transmit beam;
a first receiver on a first side of the first transmitter, the first receiver configured to receive a first component of a first return beam from reflection of the first transmit beam by an object;
a second receiver on a second side of the first transmitter, the second receiver configured to receive a second component of the first return beam;
a second transmitter configured to output a second transmit beam, the second transmitter on the second side of the first transmitter, the second transmitter spaced from the first transmitter by a distance greater than or equal to 75 micrometers (μm) and less than or equal to about 130 μm; and
one or more processors configured to determine at least one of a range to the object or a velocity of the object based on the first component, the second component, and a second return beam from reflection of the second transmit beam by the object.
