Based on autoregression(AR) model in phase domain, this paper proposes a novel impulsive interference(IMI) detection algorithm for over-the-horizon radar. This is achieved by regarding IMI phase spectrum as complex sinusoid signal and modeling it by AR model. Then we can take the full advantage of the sinusoid signal estimation algorithm. After getting zeros of AR model transfer function, the amount of the contained sinusoid signals and their frequency parameters can be estimated. The angular value of zero is exactly corresponding to IMI position of interest. Details and improvements are also discussed in this paper. This algorithm's operational performance is evaluated using experimental data sets collected from a high frequency surface wave (HFSW) OTHR system, and is proved to be suitable for most types of IMIs.
