提出了一套完整的返回散射电离图处理方法。该方法首先利用信号与干扰的特性对电离图进行干扰去除，并对去除干扰后的电离图进行内插；其次针对电离图的特点进行噪声去除，并根据电离图的距离和频率相关性进行补偿，最后提取前沿。处理结果表明，该方法实时性好，处理效果明显。

A novel method for backscatter ionogram processing is proposed. First, interferences rejection and ionogram interpolation based on features analyzing of signals and interferences among ionogram are implemented. Second, noise reduction and ionogram restoration processing based on range-frequency cor- relation of ionogram are applied. The edge of ionogram is derived in the end. The results show that the method is practical and efficient.
