%X 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)test-bed are described.The test-bed capable of transmitting data at 96kbps with hopping rates of up to 100khops/s operates in the VHF/UHF band and keeps capability of communication under the condition in which the 60% of system working spectrum is stained.Based on Software Defined Radio(SDR)technology,the architecture uses a Direct Digital frequency Synthesizer(DDS)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.
