Abstract	Interferometry measurement technology is one of the most important methods for obtaining high precision navigation information in deep space exploration. This paper describes the principle of interferometry measurement wideband correlation signal processing method using bandwidth synthesis technology for accurately extracting the delay of spacecraft angle location information. Bandwidth synthesis technology extends analysis bandwidth in interferometry measurement to get higher delay estimation precision compared with traditional interferometry method. Simulation experiment is finished, simultaneously¿C a connected interferometry measurement experiment system is established to sample real geosychronous satellite signal for interferometry measurement analysis in Beijing Aerospace Control Center . Finally, clear fringes and high precision delay are obtained by simulation and actual experiments, lower than ns precision is reached, these results confirm the perfect performance of interferometry measurement wideband correlation signal processing method, which can meet the requirement of high precision navigation in deep space exploration.
