| Objective: ||Develop algorithms and system designs based on laser remote-sensing to provide remote, real-time damage data for use in high energy laser (HEL) weapon systems.
|| Description: ||Algorithms and associated system designs based on active or laser remote-sensing technologies are sought for remote, rapid, and robust damage assessment for high energy laser (HEL) weapon systems. Laser technologies to be considered include laser radar, polarimetry, photometry, spectroscopy, and vibrometry, with the ultimate solution expected to fuse some combination of these and other technologies. Algorithms and system designs may utilize the properties of the HEL and/or those of a broadcast and/or tracking laser to provide real-time assessment of targets typically beyond the resolution limit for visual or imaging confirmation. The ultimate system will provide real-time sensor feedback on target damage, which when combined with target vulnerability data will provide a kill estimate, and will therefore eliminate from kill estimates the inherent uncertainties of damage simulations. Theoretical models of the interactions of sensor laser radiation with undamaged and damaged targets and clutter materials are required for the development of robust algorithms, which also require sound mathematical and statistical foundations. Characteristics of HEL damage in relevant material classes should be measured and understood on the microscopic level and related to the properties of laser radiation reflected or scattered from damaged targets. Actual or simulated laboratory data should be available to support algorithm development. System designs should specify hardware and software to support eventual field and/or laboratory mock-up demonstrations of prototype systems.
|| ||PHASE I: Develop algorithms for HEL damage assessment based on one of the following: 1) a fusion of laser remote-sensing technologies, or 2) models of sensor laser interactions with damaged and undamaged targets, supported by physical data on damage effects.
|| || ||PHASE II: Mature and expand the algorithms developed under Phase I, ensuring that damage data provided by algorithms are linked with target vulnerability data, specify and design systems in which algorithms can be tested in a field and/or laboratory demonstration, develop required hardware and software, and demonstrate with a prototype system damage assessment on a wide variety of target materials.
|| ||DUAL USE COMMERCIALIZATION: Military application: Laser-based remote damage-assessment algorithms are applicable to HEL effects vulnerability assessment for directed energy weapon (DEW) programs. Commercial application: Laser-based remote damage-assessment algorithms are applicable to automated inspection systems for industrial and homeland security applications.
