Dick reflection in microwave

WebMay 28, 2013 · If the earth is a smooth flat surface, the reflection from the earth appears at the receive antenna along with the direct signal. The interaction of those two signals cause an increase or decrease in the received signal level that is dependent on the vertical placement of the receive antenna.
