Transmitter: Emits the radar signals towards the target.
Antenna: Facilitates the transmission and reception of radar signals.
4.2. By Platform
Airborne: Includes aircraft, Unmanned Aerial Vehicles (UAVs), and spacecraft equipped with SAR systems.
Ground-Based: Stationary or mobile ground platforms utilizing SAR technology.
4.3. By Frequency Band
X Band: Offers high resolution, suitable for applications like military surveillance.
L Band: Penetrates vegetation and soil, ideal for geological and agricultural studies.
C Band: Balances resolution and penetration, commonly used in environmental monitoring.
4.4. By Mode
Single Mode: Utilizes a specific operational mode for data acquisition.
Multi-Mode: Combines various operational modes to enhance data versatility.
4.5. By Application
Defense: Military surveillance, reconnaissance, and target identification.
Commercial: Environmental monitoring, agriculture, urban planning, and disaster management.
