Abstract
The advantages of software receiver are its flexibility, better performance on system update and algorithm optimization. This paper mainly focused on study a software receiver which could be used in GNSS-R research, not only gives the structure of the signal collection system, but also describes the design of the software receiver system. The open-loop tracking method and FFT-based correlation power processing method of the reflected signals are introduced in the paper. The data analysis result of the signal processing experiments shows that the design of the GNSS-R software receiver can provide reliable and effective correlation data of the reflected signals, and can be used as an effective tool for the further study of GNSS-R.
