介绍了一种用于电离层等离子体不规则空间分布成像的多接收机雷达技术，并用Jicamarca射电天文台赤道电喷流数据进行了验证。以几秒钟的时间分辨率获得的图像可以监测雷达视场内不规则结构的时间演变。白天的电喷射图像包含局部不规则斑块的特征，这些不规则斑块以大约离子声的速度在东西方向漂移。
A multiple-receiver radar technique for imaging the spatial distribution of ionospheric plasma irregularities is introduced and demonstrated with equatorial electrojet data obtained at the Jicamarca Radio Observatory. The images obtained with a few seconds time resolution enable the monitoring of the temporal evolution of the irregularity structures within the radar field of view. Daytime electrojet images contain signatures of localized irregularity patches which drift in the east-west direction at about the ion-acoustic velocity.
