The assumption that the electron temperature is approximately equal to the ion temperature is not rational during the high frequency (HF)heating in low ionosphere region.Thus,using the theoretical formula of incoherent scatter spectra with collisional plasma,the incoherent scatter data are analyzed during ionosphere heating at 91.7 km height on August 15th 2006.The enhancements of electron temperature are obtained,and the incremental percent is up to 37% and 46% at the universal time of 10:22 and 10:30,respectively.By using the same initialization value,the ionosphere heating process is simulated by Ohmic theory and the experimental results are basically consistent with the simulation.
