Abstract	A new high-frequency (HF) radio prototype based on dynamic spectrum anti-jamming (DSAJ) technology was recently developed. DSAJ applies the opportunistic spectrum access concept of cognitive radio to the anti-jamming communications. Making use of the properties that there are many “spectrum holes” within HF band where no jamming exists or the power of jamming is below a particular threshold, and durations of the spectrum holes in each day are correlated, DSAJ is able to perform real-time transmit frequency selection and system parameter adjustment by detecting spectrum holes in its system bandwidth and tracking the variations of jamming in the spectrum holes. This prototype achieves many desirable features such as anti-interception, anti-jamming, optimum transmit frequency determination and uninterrupted communication, all of which have been validated via lab and field tests.
