Abstract Plasma blob is generally a low‐latitude phenomenon occurring at the poleward edge of equatorial plasma bubble (EPB) during post‐sunset periods. Here we report a case of midlatitude ionospheric plasma blob‐like structures occurring alon

When ground-based radar and range-Doppler algorithm are used to image the nearside of the Moon, it is inevitable to encounter the problem of "north-south ambiguity". This is because when the range-Doppler imaging algorithm is used to image a rotating
