The objective of the Begur 2012 campaign was to collect digital
satellite TV signals at X and Ku-bands reflected on the sea surface. An
up-looking parabolic dish antenna was pointed to the ASTRA satellite
cluster, and a broad beam antenna to the sea surface were the reflection
points were expected. Antenna polarizations were linear.
The set-up was mounted on a scaffold to avoid obstruction by nearby
vegetation, and the experiment extended over three days.
The PARIS interferometric technique was employed, delivering complex
cross-correlation waveforms between the direct and the reflected signals
with 1 millisecond coherent integration time. Observations were done at
different receiver bandwidths spanning from 4 MHz to 40 MHz.
