| Abstract: | Based on power inversion algorithm, a GPS real-time anti-jamming system composed of the Virtex-4 and TMS320C6416T hardware platform has been finished. In addition,an improved method which is easy to implement is also proposed. The algorithm is implemented on the architecture which is made up of double FPGA＋DSP. Experimental results show that the target position which can＇t be found without anti-jamming will be located precisely with ordinary receivers after the GPS signals with blanketing jamming have been passed through our real-time anti-jamming system. Lots of advantages lies in this system such as： good compatibility, accurate positioning etc. |
