Durden, Stephen L.; Klein, Jeffrey D.; Zebker, Howard A., 1992, "Measurement And Simulation of Signal Fluctuations Caused By Propagation Through Trees", https://hdl.handle.net/2014/36685, USA, JPL Open Repository
We present measured fluctuations of UHF, L-band, and C-band signals that were transmitted from the ground through a forest canopy to an airborne radar. By use of a transmitter in the open, we are able to derive both magnitude and phase fluctuations. We then propose a simple Monte... |
