| 摘 要： | 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。

| Abstract: | Backscatter sounding of ionosphere works in high frequency band.The external dense interferences 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 interference cancellation is proposed.By employing the measured data,the results show that the proposed method is effic... |
