Retrieved from Wikipedia CC BY-SA 3.0 It also provides a system known as tropospheric scatter, which allows for long-range microwave radio communication. Times, Sunday Times This next generation microwave radio platform combines antenna, radio part, and the mounting brackets into a single unit. Retrieved from Wikipedia CC BY-SA 3.0 In microwave radio relay, microwaves are transmitted between the two locations with directional antennas, forming a fixed radio connection between the two points. Retrieved from Wikipedia CC BY-SA 3.0 Its use seems to have decreased in recent years with the number of microwave radio drums (dishes) declining. Retrieved from Wikipedia CC BY-SA 3.0 Sites had commercial power but many lacked reliable telephone lines or microwave radio connectivity. Retrieved from Wikipedia CC BY-SA 3.0 Microwave sensor will send high frequency micro waves in area and will check for their reflected patterns. Retrieved from Wikipedia CC BY-SA 3.0 Microwave sensor has high sensitivity as well as detection range compared to above sensors. Retrieved from Wikipedia CC BY-SA 3.0 To satellite microwave sensors, surface melt appears to be open water rather than water on top of sea ice. Retrieved from Wikipedia CC BY-SA 3.0 In the latter technique, performance generally improves in powders and low dielectric media that are not good reflectors of electromagnetic energy transmitted through a void (as in non-contact microwave sensors).
