Некоторые Вопросы Физики Ионосферы I. Флуктуации Электронной Плотности И Рассеяние Радиоволн

To explain spread echoes from the F region the concept of aspect sensitivity was incorporated in our derivations of h′f curves using the assumption that the magnetoionic components can be treated separately. The shape of the h′f curves, as well as the extent of range and frequency spreading, was deduced for ionospheric stations located at various magnetic latitudes. The requirements of aspect sensitivity restrict the solid angle containing the echo rays to a wedge with its apex line running east‐west through the transmitter location and with its angle determined by the dip angle. At the magnetic north the wedge opens flat, and at the magnetic equator the wedge degenerates into an east‐west flat fan. The model does not lead to an explanation of a large class of observed spread F in the northern and middle latitudes. At the magnetic equator, however, the model is potentially capable of clarifying the observed spread F of a type shown in this paper.
