Sensor Fusion TechnologyAssessment
Objective:• Assess the state-of-the-art in small arms fire control
systems with, • Maturation projection• Outline a future road map.
Sensor Fusion TechnologyAssessment
Image Intensification
Thermal Imaging EO/IR Fusion Example
Project Approachto Sensor Fusion Assessment
The three parts consist of •Part One – Survey Assessment of Current Systems and Activities,
Completed; Over 125 reports identified. Addition areas of Display and Power Supplies supplement survey.•Part Two - Technology and Performance Assessment (includes discussion on Measures of Performance and Environment and Physical limits of Performance and Opportunities)
Complete•Part Three – Projection on Full Integration for a full complement of Sensor Fusion Target Acquisition/ Fire Control Systems. (Near, Mid & Far Term)

Amplify and convert to video signal
Candidate Technologies for LLL Imaging (ITT)
• Sensor function is to create an video image based on signal inputs down to overcast starlight environment(4e-7 fL sensor illumination)
• Head mounted applications need light weight, compact, high MTF performance, low power, and low cost sensors
• Digital output desired for input into fusion systems

Note: Increase in pixels have a associated cost and power increase
Value Model (selected Figure of Merit)
Task II
• Based on Multi-Objective Decision Analysis• A Means To Choose/Decide Among Competing Alternatives by
– Defining Objectives and Measures Relevant to a Decision• Quantitative• Qualitative/Subjective
– Organizing Those Objectives and Measures • Hierarchical Value Tree
– Rating Their Importance• Weights Assigned by Operational Subject Matter Experts (SME)
– Scoring Performance of Competing Alternatives on Each of the Chosen Measures
– Comparing Overall Desirability on a Consistent, Numerical Scale
What is a Value Model?

Slide 22 of IPR #II Mod’d
• USMC Mission: Provide Humanitarian Aid to Local Populace
– Distribution Point at Pier– Persons Processed at Main Gate
• Marine Corps Forces– Reinforced Rifle Platoon
• 2 HMMWVs with M2 HMGs• Scout/Sniper Team• Roving Rifle Squad
• Indigenous Persons– Innocent Civilians (72)
• Non-Hostile (Seeking Food)• Proceeding Toward Port Area• If Challenged, Will Stop, Show ID Papers
And Proceed Toward Main Gate– Terrorists (24)
• Seek To Cross Defended Perimeter And Disrupt Aid Effort
• Avoid Main Gate• If Challenged, Fled But Not Fight (with
Marines in Pursuit)– Movement Began at Random Times
from Random Locations • Model fusion as sequential process (detect > pursue > acquire)
– Use Pdetection for IR devices– Use Precognition for LLL devices
Use of Pythagoras in an AT/FP Scenario
Projection on Full Integration of Target Acquisition Fire Control Small Arms
Task III
Utilize the Value Method to define sensitivity of effectiveness that includes multi aspects of consideration (maturity, technology, use, size, weight, power, weapon –sensor linkages, etc.)Task III technology forecast characterization
Not relevant eliminate from considerationMonitor: relevant, yet not mature and not ready for investmentDefine Further; opportunities for investment
