Multipath Fading
In the context of aerospace engineering, Multipath Fading refers to the phenomenon where radio signals reach the receiving antenna by two or more paths. This occurs due to the reflection, diffraction, and scattering of the radio signal off various objects such as buildings, the ground, and atmospheric particles. In aerospace communication systems, this can be caused by reflections from the Earth's surface, the aircraft's body, or other nearby aircraft. The multiple signal paths can cause constructive or destructive interference at the receiver, leading to fluctuations in the received signal strength, known as fading. This can significantly impact the performance of wireless communication systems used in aerospace applications, such as satellite communication systems, aircraft communication systems, and unmanned aerial vehicle (UAV) communication systems. To mitigate the effects of multipath fading, various techniques can be used, including diversity techniques (such as spatial diversity, frequency diversity, and polarization diversity), adaptive equalization, and channel coding.
