... drilling derrick. Two radar frequencies are required to extract wave properties from sea states likely to be encountered offshore (25.4 Mhz for Hs < 3.5 m and 6.8 MHz for Hs > 3.5 m). * Development of system control software to enable the system to acquire and process the radar signals in real...
