Which device is a ground-fixed emitter used to track missiles and satellites?

• A. PAVE PAWS
• B. Ground Satellites
• C. Field-deployable
• D. Medical Diathermy

Answer: (A)

A ground-fixed emitter used to track missiles and satellites is a stationary radar system. PAVE PAWS is such a system—the fixed, ground-based, high-power phased-array radar designed for early warning of ballistic missiles and for tracking space objects. It stays in one location and uses electronically steered beams to monitor targets without needing to move the antenna structure. The other options don’t fit: Ground Satellites are objects, not devices; field-deployable refers to portable systems that aren’t fixed to one site; medical diathermy is a therapeutic RF device for heating tissue, not for tracking missiles or satellites.
