Planning for DWL Airborne Demonstration - Discussion

Ken MillerLidar Working GroupMonterey CAFebruary 7, 2008

2

Topics

• Discuss airborne mission possibilities– Capabilities needing demonstration– Approximate schedule– Campaign opportunities

3

Airborne Objectives

• Advance instrument TRLs– Performance and functionality– Robustness and reliability

• Demonstrate technology for space mission– DD & Coherent subsystems and components– Hybrid DWL data

• Down-looking• High altitudes• Validate atmosphere and instrument models• Signal processing

4

Airborne Objectives 2

• Demonstrate technology– Optics

• Separate for Coherent and Direct Detection• HOE for Direct Detection

– Scanners (Step-stare, not multiple fixed apertures)• Calibration and Validation

– Cross-validation of DD & Coherent– Other instruments and models

• Overfly ground instruments• Underfly satellites

5

Airborne Objectives 3

• Science Campaigns– Hurricane Genesis Mission 2010– Forecast impacts– Hurricane studies

• Future Operational Use: hurricanes, winter storms?

6

Status

• Recent NASA planning decisions– Provides some direction– Includes

• WB-57 flights for TWiLiTE• DC-8 hybrid shirtsleeves flight

• Funded– TWiLiTE DC-8 accommodation, flight test?– DAWN DC-8 readiness, flight test?

7

Status 2

• Planned – Hybrid DC-8– Engineering flights– Hurricane Genesis Mission 2010

• Beyond current planning– WB-57 TWiLiTE campaigns– DC-8 hybrid other than Hurricane Genesis– WB-57 autonomous hybrid capability and high

altitude flights– UAV flight

Variations

• Sources of funding for measurement campaigns• UAV – Global Hawk• Joint flights with other lidars

14

Airborne Shared Optics Unlikely

• Aircraft– Not needed?– Would limit flexibility

• Shared optics in GWOS Space demonstration
