电离层返回散射工作在高频频段，密集的外部干扰如短波通信、广播电台及大气噪声等污染了接收数据，严重影响返回散射电离图的判读。利用外部干扰的空时特性，提出了一种自适应波束形成．干扰对消级联去干扰的方法。对实测数据的处理结果表明这种方法的有效性和实用性。

Backscatter sounding of ionosphere works in high frequency band. The external dense interfer- ences in the HF band, such as shortwave communication, broadcast, air noise and so on, contaminate the received data, affect the interpretation of backscatter ionogram. Based on Space-Time characteristics of interference an adaptive interference mitigation method utilizing adaptive beamforming and adaptive in- terference cancellation is proposed. By employing the measured data, the results show that the proposed method is efficient and practical.
