Russian SHAREABLE DATA CENTER Institute of Solar-Terrestial Physics SB RAS . ... A most promising problem is to investigate the interaction of two VHF powerful radiowave beams in the ionosphere, whose difference frequency is equal to the plasma frequency in some ionospheric area (that is, the difference frequency is taken in the range 1-8 MHz). ... Two-frequency interaction effects are based on radiowave non-linear mixing, which is rather complicated when describing and modelling the experiment. ...

Next: A Plea to Up: Some Problems of Practical Previous: Problems of Fourier . I would like to spend the rest of my time showing an example of the kind of dilemma one can get into when doing restorations. In this particular case we were dealing with an FOC ultraviolet image of the center of M31, and a PC V -band image of the same region, scaled, rotated, and aligned. We wanted to take the quotient of the two images, to look for color effects. ... Image A has low , while B has high . ...
