  • Compared with vertical heating, oblique ionospheric heating has advantages of higher flexibility, wider effect range and more practicable operability. In this paper, based on the energy conservation equation and continuity equation of electron, the physical model is built for lower ionosphere heated by oblique radio wave by considering Ohm absorption in the non-deviated section, and oblique heating in low ionosphere over Nanjing district is simulated using the background parameters obtained by IRI-2007 and NRLMSISE-00 models. The results show that heating effect increases when incident elevation angle and effective radiated power increase. The rising amplitude of electronic temperature and density decreases when the frequency of radio wave increases. The perturbation amplitudes of electron temperature and density caused by X mode are bigger than those caused by O mode, and X mode can make electron temperature and electron density reach a steady state more quickly than O mode. Within a certain range, the radio wave with smaller incident elevation angle, lower frequency and larger effective power can make electron density reach a steady state more quickly, and the latter two can also accelerate the process of electron temperature to reach stability. The time that electron temperature to reach stability varies singlet with elevation angle of incident electromagnetic wave, and will be a maximum as the elevation angle is 62°.
