Study on marine blended waveguide inversed by radar sea clutters

Over-the-Horizon detection of atmosphere duct can be realized by the OTHR, in order to increasing the spread distance of radar electromagnetic. The calculation of five-parameter refractivity algorithm on getting hybrid duct inversion of RFC (Refractivity from Clutter) was introduced in this paper, and then the application was decrypted details. As the five-parameter algorithm is fit to get multi-duct atmosphere modified refractivity profile, it also can get the high altitude atmosphere refractivity profile, which provides reference to the further study of RFC.
