  • Method of determining ionospheric reflection height
    Patent number: 4011565
    Abstract: A method for determining the ionospheric reflection height from doppler measurements made over an oblique radio transmission involving reflection of signals from a boundary. This method makes use of multi-hop reflections. The unknown motion of the reflection boundary is eliminated by taking the doppler-shift ratio for a pair of transmission hops. The height of the reflection boundary may be computed from this ratio for the particular distance that separates transmitter from receiver. The equations used follow from relatively simple geometrical considerations derived from spherical boundaries.
