Filter for noise reduction in detection in remote sensing systems

Abstract

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.
