Beobachthung der Brillouin-Instabilität in der Ionosphäre

Descripción del Articulo

Observations of weak stimulated Brillouin scattering with the 50 MHz incoherente scatter radar at Jicamarca are described. The non-linear interaction uf the upgoing radar wave with the downcoming waves, incoherently backscattered fromm greater heights, causes an asymmetry in the incoherent "ion...

description Observations of weak stimulated Brillouin scattering with the 50 MHz incoherente scatter radar at Jicamarca are described. The non-linear interaction uf the upgoing radar wave with the downcoming waves, incoherently backscattered fromm greater heights, causes an asymmetry in the incoherent "ion" backscatter spectrum. For a given antenna aperture this asymmetry increases with increasing power and decreasing frequency of the rdar. The theoretically predicted effect was unambiguuosly verified, using 3 msec pulses and long integration time. Model calculations show good agreement with the observations.
