高频地波雷达（ＨＦ－ＧＷＲａｄａｒ）作为探测超视距目标的有效手段在海防武器系统中担当重要的角色。高频段电磁环境恶劣，近区雷电在这一频段激发的天电噪声对ＨＦ－ＧＷ雷达的正常工作构成了严重干扰。通过分析雷电在ＨＦ－ＧＷ雷达多普勒域表现的奇异性，本文提出了利用小波变换在多普勒域检测雷电干扰的方法和一种抑制雷电干扰的方案。现场实验表明本文方法有效提高了ＨＦ－ＧＷ雷达抗雷电干扰的能力
High-frequency ground wave radar (HF-GWRadar) plays an important role in the anti-aircraft defense system as an effective means of detecting over-the-horizon targets. Due to the harsh electromagnetic environment in the high frequency band, the noise caused by near-area lightning in this band poses serious interference to the normal operation of the HF-GW radar. By analyzing the singularity of thunder and lightning in the Doppler domain of HF-GW radar, this paper presents a method of detecting thunder and lightning interference in Doppler domain by using wavelet transform and a scheme of suppressing thunder and lightning interference. Field experiments show that the proposed method can effectively improve the ability of HF-GW radar to resist lightning interference
