No, microwaves used in radar for aircraft are not powered by cell towers. The technology used in aircraft radar and cell towers are separate and distinct.
Aircraft radar systems are typically part of the aircraft's avionics and are used for navigation, weather detection, and collision avoidance. These radar systems use electromagnetic waves in the microwave frequency range to send out pulses and receive reflections, allowing the aircraft to detect other objects in its vicinity.
On the other hand, cell towers use microwave signals to transmit and receive data between mobile devices and the cellular network. These microwaves are used for wireless communication, enabling mobile phones and other devices to connect to the internet and make calls.
While both radar systems and cell towers use microwaves, their purposes and functions are entirely different. Aircraft radar systems are essential for aviation safety and navigation, whereas cell towers support our daily mobile communications. The two technologies operate on different frequency bands and have different power requirements and purposes.
