Prediction of radar coverage under anomalous propagation condition for a typical coastal site - a case study... The field strength and radar coverage for different conditions of the typical coastal site prevailing a standard and inhomogeneous surface duct demonstrates the sensitivity of the model with the inhomogeneous and homogeneous atmosphere....
Investigation on the inversion of the atmospheric duct using the artificial bee colony algorithm based on opposition-based learning... Taking the inversion of the surface duct using refractivity from clutter (RFC) technique as an example to validate the performance of the proposed OGABC, the inversion results are compared with those of ...
Estimation of surface duct using ground-based gps phase delay and propagation lossThe propagation of Global Positioning System (GPS) signals at low-elevation angles is significantly affected by a surface duct....
