1. An imaging system comprising:
- a sensor comprising an array of pixels, each individual pixel of the array of pixels configured to detect optical radiation;
a multispectral filter disposed within an optical path of the sensor, the multispectral filter comprising a plurality of filters, wherein each individual filter of the plurality of filters is transmissive to optical radiation having a wavelength within a wavelength range;
a polarizing filter disposed within the optical path of the sensor, wherein the polarizing filter is capable of filtering optical radiation at a plurality of polarization states;
a processor; and
a non-transitory computer-readable medium storing instructions that, when executed by the processor, causes the processor to;
characterize at least one obscurant that is present within an environment; and
based at least on a obscurant characterization, perform one or more of the following;
adjust the multispectral filter;
apply a selected polarization state of the polarizing filter; and
select an exposure time for the sensor.

Abstract
Systems and methods for characterizing an obscurant and imaging a target are disclosed. In one embodiment, a method of imaging a target includes characterizing at least one obscurant present in an environment, and determining, based on the at least one characterized obscurant, one or more of the following: one or more wavelengths corresponding to the at least one obscurant, a polarization state corresponding to the at least one obscurant, and a sensor exposure time corresponding to the at least one obscurant. The method further includes adjusting one or more parameters of an imagining system based at least in part on a characterization of the at least one obscurant.
