Abstract

In the last decade, using GNSS reflection (GNSS-R) signals for oceanographic remote sensing becomes a new direction in GNSS applications. GNSS-R receiver consists of direct channels for tracking signal from navigation satellite and reflection channels for acquiring the phase delay and Doppler frequency of signal reflected from the ocean. The method of GNSS-R reflection channel based on segment correlation and FFT is presented in this paper. Resources of the reflection channels decrease due to the new algorithm. Performance of the new method is simulated and analyzed.
