Question

Derive an expression for the field strength of ground wave propagation

Answer 1

Explanation:

Ground Wave propagation is a method of radio wave propagation that uses the area between the surface of the earth and the ionosphere for transmission. The ground wave can propagate a considerable distance over the earth's surface particularly in the low frequency and medium frequency portion of the radio spectrum.

Answer 2

Answer -

• Ground-Wave Propagation. The Austin-Cohen formula6 was used until about 1930 to calculate field strengths at a distance from a transmitting antenna. ... In these three equations, E1 is the field strength in millivolts per meter at one mile and P is the power input to the antenna in kilowatts.
