Angle of Incidence (AOI) Measurement Capability

Description:

OBJECTIVE: To advance the state of the art in the capability to measure angle of incidence (AOI) through the use of external sensors and techniques which may include, but are not limited to: laser range measurement, photometry, etc. DESCRIPTION: The lethality of certain weapon systems is in part a function of the AOI with respect to the target. AOI is the measured difference between weapon body axes and the target axes at impact. AOI may be a function of the attitude of the target at the moment of impact or, in the case of strike warfare, the topography of the ground or water target at the point of impact. It is estimated that AOI measurements could be obtained through the use of sensors on an orbiting platform as well as on the target itself. At present, no commercially available, off-the-shelf sensor suite exists to meet the following AOI measurement requirements: AOI 3 DOF Angle of Incidence Error RMS<1 degree each axis Steady State Position Vector Error to Store as Function of Time RMS<5 cm,<1 degree Steady State Stores 3 DOF Attitude Error RMS as Function of Time<1 degree Each Axis PHASE I: Develop a sensor concept. This effort should include a study of existing technologies for consideration in the development of the concept. PHASE II: Develop a prototype as a risk mitigation effort. Test and demonstrate this technology. The offeror shall develop viable demonstration cases by collaborating with the government or private sector entities. PHASE III: Follow-on activities could be pursued by the offeror, namely to seek opportunities to integrate the demonstrated sensor technology into commercial test articles. Commercial benefits include improved competitive opportunities for providers of aerospace platform components and sub-systems. REFERENCES: 1."Targeting At the Speed of Light", Richard L.
