🛰️ ADR-Sat v0.1 Overview

• Satellite Platform: ADR-Sat v0.1 is equipped with telescopic antennas for transmission (Tx) and reception (Rx).
• Tx/Rx Processing: Handles signal generation and echo analysis onboard.
• Downlink: Uses X-band or Ka-band frequencies to send processed data to a Ground Gateway.

📡 Active Sensing Beam

• Pulsed ADR Waveform: A directed beam (1–100 MHz) aimed nadir-pointed (straight down toward the planet's surface).
• Purpose: Penetrates through the atmosphere and into the subsurface layers.

🌍 Planetary Interaction

• Surface & Subsurface:
• The beam interacts with soil, rock, aquifers, and voids.
• These materials reflect the signal back with time delays and spectral variations.
• Echo Analysis:
• Reflected signals are captured and analyzed to infer subsurface composition, depth, and structure.

🔍 Applications

• Hydrology: Mapping aquifers or underground water reservoirs.
• Geology: Detecting faults, voids, or mineral deposits.
• Planetary Science: Could be adapted for Mars or lunar missions to explore beneath the surface.

📡 Rover ADR

• Pulsed ADR from a Rover: ADR can be deployed from a surface Rover (similar to the MARS Rover)
• Purpose: Penetrates through solid Martian rocks
