Radio Propagation Model by Reflections Off Varied Surfaces

On high frequency, radio waves can travel along atmosphere by reflecting off different earth surfaces and ionosphere. How long can the waves travel and how many times can the waves reflect off varied earth surfaces and ionosphere are the most concerned questions. Our paper aims at establishing a reliable model estimating radio waves travelling and reflecting. ignoring energy loss on ionosphere, we developed a model dealing with the situation that a point land source transmits radio waves and turbulent sea surface reflection occurs only once right after the first reflection off ionosphere. The result proves that turbulent ocean surface weakens the signal much more than calm ocean surface, leading to less reflections.
