Laser MASINT
This discipline includes both measuring the performance of lasers of interest, and using lasers as part of MASINT sensors. With respect to foreign lasers, focus of the collection is on laser detection, laser threat warning, and precise measurement of the frequencies, power levels, wave propagation, determination of power source, and other technical and operating characteristics associated with laser systems strategic and tactical weapons, range finders, and illuminators.
In addition to passive measurements of other lasers, the MASINT system can use active lasers (LIDAR) for distance measurements, but also for destructive remote sensing that provides energized material for spectroscopy. Close-in lasers could do chemical (i.e., materials MASINT) analysis of samples vaporized by lasers.
Laser systems are largely at a proof of concept level. One promising area is a synthetic imaging system that would be able to create images through forest canopy, but the current capability is much less than existing SAR or EO systems.
A more promising approach would image through obscurations such as dust, cloud, and haze, particularly in urban environments. The laser illuminator would send a pulse, and the receiver would capture only the first photons to return, minimizing scattering and blooming.
Use of LIDAR for precision elevation and mapping is much closer, and again chiefly in urban situations.
