WebAll the E-region plasma line observations at Arecibo showed narrow spectral features at 430 MHz ± fHF where fHF is the HF pump frequency. At the EISCAT facilities, enhanced E-region ion lines were observed with the UHF incoherent scatter radar by Schlegel et al. (1987), but spectra were not reported and there were no plasma line measurements. WebIncoherent scatter radar theory is the most well recognized applied technique for studying the Earth's ionosphere, which was first proposed by Professor William E. Gordon in 1958. …

Weberally means scattering that is stronger than incoherent scatter but weaker than total reflection. The detection of coherent radar scatter generally implies the existence nonthermal irregularities in the plasma, indicative of free energy, waves, and instabilities. The resulting echoes can be very strong, http://sirius.bu.edu/aeronomy/2006JA012051_larsen.pdf irish american orthopaedic society https://todaystechnology-inc.com

A powerful radar can detect the incoherent backscatter from the free electrons in and above the earth's ionosphere. The received signal is spread in frequency by the Doppler shifts associated with the thermal motion of the electrons.
