Abstract:
The performance of high-frequency radars is known to suffer from transient interference and noise, such as cosmic noise, lightning, meteor echoes, man-made impulse bursts, etc. Traditional interference suppression methods need to detect the location of transient interferences before mitigating them, and they process the data of each range cell separately without exploiting the information of other range cells. On the other hand, the traditional methods cannot effectively suppress the weak transient interference and noise. In this letter, we propose a novel interference suppression method based on the supervised matrix completion. Unlike the traditional methods, the proposed method does not require the interference detection step and can use the prior information from other range cells. The proposed algorithm can suppress not only the interferences, including the strong and weak ones, but also the noise. Processing results of real data have demonstrated the effectiveness of the proposed method.
