1. A system, comprising:
a first transceiver comprising:
a first beam emitting subsystem configured to generate a first plurality of coherent beams,
a first detector to receive radiation, and
a first optical assembly having an aperture and configured to:
direct the first plurality of coherent beams through the aperture towards a target,
collect, via the aperture, radiation reflected from the target, the collected reflected radiation including at least a first component of radiation corresponding to the first plurality of coherent beams and a second component of radiation corresponding to a second plurality of coherent beams impinging on the target, and
guide the second component of radiation to the first detector,
wherein the first detector is configured to generate, from the second component of radiation, a signal indicative of an intensity of radiation impinging on the target corresponding to the second plurality of coherent beams;
a second transceiver comprising:
a second beam emitting subsystem configured to generate the second plurality of coherent beams,
a second detector to receive radiation, and
a second optical assembly having an aperture and configured to:
direct the second plurality of coherent beams through the aperture of the second optical assembly towards the target,
collect, via the aperture of the second optical assembly, radiation reflected from the target, the reflected radiation collected by the second optical assembly including at least a first component of radiation corresponding the first plurality of coherent beams and a second component of radiation corresponding to the second plurality of coherent beams, and
guide the first component of the reflected radiation collected by the second optical assembly to the second detector,
wherein the second detector is configured to generate, from the first component of the reflected radiation collected by the second optical assembly, a signal indicative of an intensity of radiation impinging on the target corresponding to the first plurality of coherent beams; and
a control subsystem associated with the first transceiver and the second transceiver, the control subsystem configured to: modify at least one parameter of the first transceiver based on the signal generated by the second detector, and modify at least one parameter of the second transceiver based on the signal generated by the first detector.
