What is the maximum range of the Multi-mission Hemispheric Radars?

• A. 30km
• B. 20km
• C. 40km
• D. 50km

Answer: (A)

The maximum range is set by how far the radar can detect a target with enough signal above the noise and clutter under typical operating conditions. For the Multi-mission Hemispheric Radar, the combination of transmit power, antenna gain, operating wavelength, receiver sensitivity, and processing capabilities yields a practical detection limit around 30 kilometers. Beyond that distance, the returned signal becomes too weak to distinguish reliably from background, making detections unreliable. The system is designed for broad hemispheric coverage with a balance of range, resolution, and reliability, rather than long-range detection, so 30 kilometers represents the upper limit built into its specifications. Options requesting shorter or longer ranges would imply capabilities that don’t align with the hardware and mission constraints of this radar.
