Outline of Final Research Achievements

The next generation incoherent scatter radar (EISCAT_3D) will enable us to investigate three-dimensional structures of the upper atmosphere, and we need several verifications of multi-static phased-array techniques for its realization. In this study, we performed multi-static and multi-beam observations using the current EISCAT VHF radar and the proto-type phased-array receiver (KAIRA). We succeeded in receiving 2 beams of the VHF radars with the KAIRA receiver separately, and also compared data obtained from the multi-narrow beam observations with results using post-beam steering techniques.
