Microwave absorption losses
WebLoss of radar energy due to atmospheric absorption, when propagation is through the clear atmosphere or rain, is usually small for most systems operating at microwave frequencies. Interference Signals from nearby radars and other transmitters can be strong enough to enter a radar receiver and produce spurious responses. WebMicrowaves are electromagnetic waves that have a frequency range from around 0.3 GHz (there is no actual specified lower frequency limit) to 300 GHz with corresponding …
