Development of a Cost-Effective Airborne Remote Sensing System for Coastal Monitoring

Area of Science:

• Coastal Zone Management
• Environmental Monitoring
• Remote Sensing Technology

Background:

• Coastal areas are ecologically vital but face significant environmental challenges from climate change and human activities.
• Existing monitoring methods like space-borne remote sensing and in-situ measurements have limitations in spatial/temporal resolution and data coverage.
• Effective monitoring is crucial for understanding and managing these dynamic coastal ecosystems.

Purpose of the Study:

• To implement a cost-effective airborne remote sensing system for comprehensive coastal area monitoring.
• To develop calibration techniques and geophysical model algorithms for enhanced data acquisition.
• To observe key coastal environmental parameters including intertidal topography, sea surface current, sea surface temperature, and submarine groundwater discharge.

Main Methods:

• Deployment of a specialized airborne remote sensing system equipped with synthetic aperture radar and thermal infrared sensors.
• Development and application of advanced calibration techniques for sensor data.
• Implementation of geophysical model algorithms to process sensor data for specific coastal parameters.

Main Results:
