Global Navigation Satellite System Reflectometry (GNSS-R) is a new approach for earth observation using signals of opportunity in a bistatic configuration. The system, in the configuration of interest, exploits the 10 bits PN sequence of the GPS system to generate Delay/Doppler maps that are useful for monitoring the sea state. One of the open problems is that the achievable delay and Doppler resolution is limited by the GPS waveform. We will show that, exploiting a MUSIC-based algorithm, it is possible to move further the limits for the achievable delay and Doppler resolution.

Abstract
Global Navigation Satellite System Reflectometry (GNSS-R) is a new approach for earth observation using signals of opportunity in a bistatic configuration. The system, in the configuration of interest, exploits the 10 bits PN sequence of the GPS system to generate Delay/Doppler maps that are useful for monitoring the sea state. One of the open problems is that the achievable delay and Doppler resolution is limited by the GPS waveform. We will show that, exploiting a MUSIC-based algorithm, it is possible to move further the limits for the achievable delay and Doppler resolution.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
