Naval Fuze Sensor Application
z Purpose:
Adapt the new generation FM-CW sensor to air target detection mission
z
Issue:
Current sensor is designed for surface detection
z
Objectives:
Keep current sensor hardware and architecture
Cope with:
• Sea clutter disturbance
• Target Radar Cross Section
Implement specific signal processing software
