In this study, we suggest a new remote sensing technique for enhanced electron density in the lower ionosphere by using the correlation between VLF whistler mode waves (daytime chorus emissions) and CNA, both observed on the ground. The ionospheric a

We have developed a controller for the imaging riometer running on a multi-task operating system. Beam scanning and data sampling of the system are controlled by the interrupt handler triggered by an external cyclic signal. We can monitor the conditi

Imaging riometer of two-dimensional multi-narrow beams is a powerful radio instrument to investigate the structure of cosmic noise absorption (CNA) in the auroral ionosphere caused by the precipitation of energetic electrons. However, the instrument
