Vehicles, systems, and techniques are provided for noise reduction in detection in remote sensing systems. Noise reduction can be accomplished, in some embodiments, by narrowing a time interval to receive return EM radiation (or, in other embodiments, EM signals representative of the return EM radiation) at a system mounted in a vehicle. The time interval can be narrowed by adjusting the time during which the system can receive the return EM radiation. In other embodiments, rather than adjusting the time interval, a processing unit can remove a portion of data representative of a signal resulting from mixing probe EM radiation and return EM radiation. The data that is removed can be representative of the signal during a leading interval of the defined period during which probe EM radiation is emitted. Such a removal can result in second data representative of the signal during a terminal interval of the defined period.

Filter for noise reduction in detection in remote sensing systems

A lidar system is described herein. The lidar system includes a transmitter that is configured to emit a frequency-modulated lidar signal. The lidar system further includes processing circuitry that is configured to compute a distance between the lidar system and an object based upon the frequency-modulated lidar signal, the processing circuitry configured to compute the distance with a first resolution when the distance is at or beneath a predefined threshold, the processing circuitry configured to compute the distance with a second resolution when the distance is above the predefined threshold, wherein the first resolution is different from the second resolution.

Lidar system that is configured to compute ranges with differing range resolutions

A laser distance and ranging (LADAR) array is provided. The LADAR array includes a plurality of LADAR modules, each LADAR module configured to scan a laser beam through a field of view (FOV) and output a signal indicative of a distance between each LADAR module and objects in the FOV that the laser beam is incident upon, and a central processing device communicatively coupled to the plurality of LADAR modules, the central processing device configured to generate an output based at least in part on the signals of each LADAR module.
