Propagation Effects on HF Skywave MIMO Radar [PDF]

, 2014
MIMO technology has been suggested as an eective tool to overcome some of the issues typical of conventional OTH skywave radars. The advantages of the application of MIMO technology to HF Skywave radars is based on the transmission of multiple ...

Climatological model of over-the-horizon radar (CMOR) [PDF]

, 2017
Models of radar systems are required for a variety of reasons. The sophistication of these models is highly dependant on their purpose; for instance microwave radar models which are designed to be integrated into existing wargaming simulation frameworks ...

Uso delle forme d'onda FMCW nei sistemi radar OTH [PDF]

In questa tesi verrà trattato il principio di funzionamento dei radar OTH con particolare riferimento ad un tipo di modulazione dell’onda trasmessa (Frequency Modulated Continuous Wave, che per semplicità in seguito scriveremo come FMCW).
