The two most commonly used radar remoting configurations are

• A. Cable/land lines and radio microwave links
• B. Cable/land lines and satellite links
• C. Wireless optical links and coaxial lines
• D. Fiber optic links and radio relay

Answer: (A)

Radar remoting transfers data from a remote radar site to a central processing location, and the two most common ways to do this are through cable/land lines and radio microwave links. Cable/land lines provide a stable, high-bandwidth path where lines can be laid or leased, making them economical for moderate distances with predictable performance and good security. Radio microwave links offer flexible, long-distance connectivity where laying cable isn’t practical, using line-of-sight paths to carry data at high rates, though they require proper alignment and can be affected by weather.

Satellite links exist but add latency and cost, making them less typical for routine radar data transport. Other options like wireless optical links or coaxial lines have limitations—weather sensitivity and alignment issues for free-space optics, and distance/bandwidth constraints for coax—while fiber is widely used today, the traditional pairing most commonly seen is land lines and microwave links.
