摘要
研究了轨道高度对天基预警雷达地杂波多普勒频率的影响。首先建立了天基预警雷达杂波多普勒频率模型,在常规杂波多普勒频率模型的基础上,引入了轨道高度这一参数,推导了偏航角、偏航幅度和多普勒频率随轨道高度变化的公式;接着通过理论分析,得出了偏航角、偏航幅度和多普勒频率随轨道高度变化的规律;最后通过仿真验证了轨道高度对偏航角、偏航幅度和多普勒频率的影响。研究结论可为天基预警雷达选择运行轨道高度提供理论依据。
The system in this paper has researched the influences that orbital altitude has on space-based early warning radar（ SBE- WR） Doppler. Firstly, the clutter model of SBEWR Doppler was developed. Then the parameter of orbital altitude was introduced and the relationship was derived between crab angle, crab magnitude, Doppler shift respectively and orbital altitude, obtained the law between these parameters and orbital altitude through the deep analysis and the conclusion was verified by simulations. The conclusions can provide theoretical foundation of selections for SBEWR＇s orbital altitude.
