It has been shown using simulated data that phase estimation of cross-track multibaseline synthetic aperture radar (SAR) interferometric data was most efficiently achieved through a maximum likelihood (ML) method. In this paper, we apply and assess t

Multifrequency RF-measurements and characterisation of propagation conditions in the maritime boundary layer

Autor: Paul Colditz, Gregor Biegel, Thorsten Brehm, Jorg Forster, Andreas Danklmayer

Publikováno v: 2016 IEEE International Symposium on Antennas and Propagation (APSURSI).

In the maritime boundary layer, air-sea interaction processes have an important impact on radar propagation. The radar range performance near the sea surface depends on meteorological and sea surface conditions. Strong gradients of humidity and tempe
