Bistatic radar remote sensing based on the reflected signals of global positioning satellite system (GNSS-R) in recent years, the international development of a new concept of microwave remote sensing methods . Sea, land surface reflection surface of the reflection signal , remote sensing measurements of sea surface wind field , surface humidity , salinity , forest cover and other parameters , inversion and detection using GNSS satellite signal . This paper systematically expounded the theory of GNSS reflected signal receiving and processing , focusing on the FPGA reflected signal and DSP processor designed according to the requirements of the reflected signal receiving and processing system , including design simulation and processor sub-module of the correlator the processing flow of the direct signal and the reflected signal . The main work and innovative research results are as follows : 1 value resolution selection , design related value resolution to select the module and mode selection module , Depending on the demand for physical retrieval output resolution value and a correlation power value. 2 in the relevant aspects of the reflected signal is demodulated , the design of fast demodulator and fast correlation replace the traditional processing reflected signal demodulated and the data related multiplications , to shorten the delay time of the system , reducing the chip logic resources loss, so that the receiver functions more flexible expansion . Designed in the generation of C / A code of the reflection signal processing delay of C / A code generator , so that the receiver does not need to consider the height of the application only needs to be generated in the DSP processor auxiliary reflection channel delay needed C / a code to reduce the occupation of hardware logic resources , and more suitable for airborne and spaceborne receivers .
