[PEM09-P11] D- and E-region ISR spectra measured with EISCAT radars
Keywords:ionosphere, Incoherent scatter radar, plasma
We have investigated ISR spectra in the D- and E-region using the latest techniques of the EISCAT UHF and VHF radars located in Tromsø. Previous studies indicate that the EISCAT UHF and VHF radars have limitations of plasma parameter derivation below 90 and 100 km altitudes, respectively. We show lower limits of reliable plasma parameter derivation using the latest pulse coding techniques of the EISCAT radars. Based on the knowledge and experience of the current EISCAT radar observations, we will discuss possibility and limitation of future E- and D-region observations of the EISCAT_3D radar.
