Anti-jamming Performance and Implementation of Ultra-Fast Frequency Hop Test-bed
Fast Frequency Hopping (FFH) communications is an important technology of anti-jamming in military applications. In this paper, anti-jamming performance and implementation of Ultra-Fast Frequency Hopping (UFFH) testbed are described. The system provides the highest hopping rate reported to date and keeps capability of communication under the condition in which the 60％ of system working spectrum is stained. The test-bed capable of transmitting data at 96kbps with hopping rates of up to 100khops/s operates in the VHF/UHF band. Based on software defined radio technology (SDR), the architecture uses a direct digital frequency synthesizer (DDFS) to implement demodulation and modulation of frequency hopping (FH) signal. Furthermore, different arithmetic of digital signal processing and parameters could be software configured because of the high performance analog-to-digital converter (ADC) and the super-heterodyne architecture. Finally, it is showed by the result of measure and simulation that UFFH test-bed has a robust anti-jamming performance.
