1. A system comprising:
a first sensor and at least one second sensor each arranged on a vehicle to perform object detection within an overlapping coverage area,
the first sensor comprising:
a transmitter configured to radiate a first periodic signal that has a radiation pattern including a main lobe for detecting objects in the coverage area, and a plurality of side lobes for exchanging data sensor-to-sensor on a side communication channel formed between the first sensor and the second sensor,
the transmitter being further configured to modulate the first periodic signal when the first periodic signal reflects off an object to encode object data relating to that object on a carrier signal that is transmitted sensor-to-sensor through the side communication channel;
the second sensor comprising:
a receiver configured to detect the carrier signal from the side lobes of the radiation pattern of the first sensor to demodulate the carrier signal and decode the object data transmitted from the first sensor.
