Mikrowelleninterferometrie

Mikrowelleninterferometrie is a technique used in radio astronomy and geodesy to measure the distance between two points with high precision. It operates by transmitting microwaves from one point, called the transmitter, and receiving them at another point, called the receiver. The microwaves travel through the atmosphere and are reflected off a target, such as the Moon or a satellite, before being received back at the receiver. The time it takes for the microwaves to travel to the target and back is measured, and this time delay is used to calculate the distance between the transmitter and receiver.

The precision of Mikrowelleninterferometrie is achieved by using a technique called phase comparison. The microwaves are transmitted and received as a continuous wave, and the phase of the wave is measured at both the transmitter and receiver. The difference in phase between the two points is used to calculate the distance between them. This technique allows for measurements to be made with an accuracy of a few millimeters.

Mikrowelleninterferometrie has a number of applications in radio astronomy and geodesy. In radio astronomy, it is used to study the structure and dynamics of celestial objects, such as galaxies and quasars. In geodesy, it is used to measure the shape and size of the Earth, as well as to study the Earth's crust and mantle. It is also used in satellite navigation systems, such as GPS, to provide accurate positioning information.
