This paper presents a technique for designing a three-array HF adaptive nulling antenna system. The mono-channel scheme is adopted in this system to solve the multi-channel mismatch problem . The key technology for the whip-loop antenna, receiver, signal-processing platform and time-division is described in detail, respectively. With the multiple signal classification (MUSIC)algorithm and open-loop and close-loop adaptive method, itis shown from the experiment results that the HF adaptive antenna system can suppress interference efficiently
