摘　　要：利用二维磁化电离层欧姆加热数值模型和离散电离层背景下的射线追踪模型,对穿过高频加热电离层区域的超视距雷达(OTHR)诊断电波的波特性(主要是doppler频移和相位偏移)进行定量的分析,得到了在加热开机2 min内的诊断电波doppler频移和相位偏移的模拟结果。并结合国外相近参数的试验结果进行对比分析,给出了初步结论。A two demension Ohm heating and the ray-tracing model in the discrete theoretic model in magnetizing ionosphere ionosphere background are used to diagnose the characteristics of the Over-The-Horizon Radar （OTHR） wave quantitatively, which transmit through the heated region in ionophere （mainly about the doppler shift and the phase shift）. The simulation results about the doppler and phase shift are obtained within 2 minutes after the heater＇s on. Some conclusions are given by comparing the numerical results with the experimental data.
