The SAR (Synthetic Aperture Radar) range can vary significantly depending on the specific system and its application. Typically, SAR systems deployed on satellites or aircraft can reach ranges of tens to hundreds of kilometers. Exact range capability depends on factors such as platform altitude, radar power, and environmental conditions.
The frequency range of SAR is generally in the microwave region of the electromagnetic spectrum, encompassing frequencies from approximately 1 GHz to 40 GHz.
Common frequency bands used for SAR include L-band (1-2 GHz), C-band (4-8 GHz), X-band (8-12 GHz), and Ku-band (12-18 GHz), each offering different trade-offs between resolution and penetration capabilities.
SAR frequency refers to the specific microwave frequency at which the SAR system operates. Different frequency bands are chosen depending on the desired application; For example, L-band frequencies penetrate vegetation and soil more effectively, making them suitable for forestry and agriculture, while X-band frequencies provide higher resolution images for land mapping.

SAR radar is used for a variety of applications including Earth observation, mapping, surveillance and reconnaissance. It is particularly valuable for its ability to produce high-resolution images regardless of weather or lighting conditions, making it ideal for monitoring environmental changes, disaster response, military intelligence and assessment of infrastructure.
SAR bandwidth refers to the range of frequencies over which the radar system operates. Wider bandwidths enable higher resolution imaging.
Typical SAR systems could have bandwidths ranging from a few tens of MHz to several hundred MHz. For example, high-resolution SAR systems could use bandwidths of 100 to 400 MHz to achieve fine spatial resolution in their imagery
