Abstract

Coherent Fast Frequency Hopping (FFH) spread spectrum signals effectively improve the ability to fend off forwarding jamming and interception of a satellite anti jamming communication system. However the acquisition of FFH signal is influenced by the frequency-selective ionosphere delays. The global ionosphere grid of Vertical Total Electron Content (VTEC) is used to aid the acquisition.The ionosphere delays were modeled as functions of VTEC and elevation angles, the integrals of different hops were adjusted and accumulated accordingly thus the acquisition complexity was reduced. The energy loss caused by VTEC error is calculated and the complexity reduction of this algorithm versus TEC searching algorithm is analyzed. This research is valuable to the synchronization of satellite FFH signal on different radio bands.
