Human Surrogate Test Target


OBJECTIVE: Design, build and test a test target approximating human anatomy, capable of generating the data required to populate existing government models that predict the risk of significant injury to humans subjected to various non-lethal stimuli. DESCRIPTION: Non-lethal weapon stimuli include blunt trauma, monochromatic (laser) and broadband (flashbang) light, blast over-pressure, thermal energy, electrical current, chemical irritant (riot control agents) and electromagnetic radiation in the L, S, and W-bands. The Joint Non-Lethal Weapons Program (JNLWP) has developed a suite of computer models that predict the risk of significant injury to human targets of these stimuli, but needs an improved method for gathering the input data for these models. To effectively run these models, the JNLWP requires input data such as: sound pressure levels at the ear, the fluence and wavelength of light (including infrared) incident on the cornea and retina, pressure at many points on the body as possible, concentration of chemicals at the face, temperature at various positions (including the face) and EM field intensity. All of these need to be measured as a function of time. PHASE I: Design a human surrogate test target capable of collecting the data required to run the JNLWP"s prediction models. PHASE II: Build and test the human surrogate test target, ensuring the accuracy of generated data by validating against existing data collection systems. PHASE III: Design, develop, test and deliver a prototype system, along with detailed engineering drawing, allowing for the production of multiple test targets for use in the development and testing of non-lethal weapons. PRIVATE SECTOR COMMERCIAL POTENTIAL/DUAL-USE APPLICATIONS: Law enforcement is the primary user of non-lethal systems and would benefit the most from this development. Furthermore, such a device could be used to test the safety of commercial products, designed for any purpose. This technology can benefit from and contribute to advancements in crash test dummies.
