Coupling processes between plasma and neutral atmosphere is very important to understand the ionosphere. Inhomogeneity of plasma is the source of polarization electric field that maps very long along the geomagnetic field line. We obtained following results in our four research topics.Topic 1: Brainstorming for new studies of atmosphere ionosphere coupling processesInternational workshop was held in 2006 for intensive discussion on the topic. Future rocket experiment plan was made through the discussion. and is now proposed to JAXA/ISAS.Topic 2: F-region E-region coupling observationsWe conducted FERIX-2 observation campaign with the MU radar (F-region FAI observation), a portable radar in Sakata, Yamagata (E-region FAI observation), and an airglow imager (observation of neutral atmosphere density fluctuation), and directly compared FAIs in both regions. We found that F-region FAI has smaller scale structure that propagate northwestward along the wavefront of the larger structures. E-region FAIs tend to appear where F-region FAIs on the same field line are missing.Topic 3: Experiment of small-scale FAI structures with radar imaging techniqueWe developed the radar imaging observations of FAIs with the MU radar. We found F- and E-region coupling relationship between the E-region FAIs and MSTID in GPS-TEC. First observations of midlatitude F-region FAIs were also successful. Radar imaging flout this topic was fully utilized in the FERIX-2 observation campaign.Topic 4: Ionosphere beacon experiment between satellite/rocket and groundWe joined the ISAS sounding rocket observations in summer 2007, and conducted rocket-ground beacon experiment. We developed a new digital beacon receiver, and use it for the experiment.

血浆和中性气氛之间的耦合过程对于理解电离层非常重要。等离子体的不均匀性是极化电场的来源，它沿着地磁磁场线很长。我们在四个研究主题中获得了以下结果。主题1：针对大气电离层耦合过程的新研究的头脑风暴，于2006年举行了有关该主题的深入讨论。未来的火箭实验计划是通过讨论制定的。 and is now proposed to JAXA/ISAS.Topic 2: F-region E-region coupling observationsWe conducted FERIX-2 observation campaign with the MU radar (F-region FAI observation), a portable radar in Sakata, Yamagata (E-region FAI observation), and an airglow imager (observation of neutral atmosphere density fluctuation), and directly compared FAIs in both地区。我们发现F-Region Fai具有较小的规模结构，可以沿着较大结构的波前传播西北。 E-Region Fais往往会出现在同一场上缺少同一场上的F-Region Fais的情况下。Topic3：带有雷达成像技术的小规模FAI结构的实验，通过MU雷达进行了FAIS的雷达成像观测。我们发现gps-TEC中的E-Region FAIS和MSTID之间的F-和E-E-Region耦合关系。对中纬度F-Region FAI的首次观察也成功。雷达成像flout这个主题在Ferix-2观察活动中充分利用。主题4：卫星/火箭和地球之间的电离层信标实验，并在2007年夏季加入了ISAS Sounding Rocket观测，并进行了火箭群的灯塔灯塔实验。我们开发了一个新的数字信标接收器，并将其用于实验。
