AREPS Probability of DetectionValidation Project

• LT Greg Ray
• OC3570 Summer 2005

2
Introduction

• The Problem
• Use AREPS to accurately produce a Probability of
  Detection function for a given environment

3
Introduction

• Why is this important
• Nobody can do it yet
• Current ability to detect ducts but not predict
• Predicting ducts gives the war fighter an
  advantage

4
Data Methods

• Where and how were data collected
• Shipboard Radiosondes
• Vaisala RS80 DigiCORA software
• Shipboard Met Tower
• Collect surface environmental data
• Shore Radar AN/SPS-67
• Short-range, two-dimensional, surface-search/navig
  ation radar system

Results

• AREPS AN/SPS-67 Agree
• POD Functions are very similar
• Significant for operational forces
• Can exploit environment
• Have advantage over enemy
• Future Work
• More Validation
• More Target Platforms/Radar Models
