| Zusammenfassung |
| Recently, one of the authors (A. V. G.)
developed a theory of low-frequency plasma irregularities which are created as a
consequence of neutral turbulence in the D and lower E regions. In the following
this theory will be applied to coherent backscatter experiments with radars in a
frequency range between 5 and 150 MHz. We discuss the dependence of the
backscatter cross-section on ionospheric as well as on turbulence parameters.
The backscatter increases strongly with decreasing radar frequency. Above 15 MHz
the effects discussed here can probably only be detected by very powerful radars
with large antenna arrays. |
