摘要
根据卫星导航无线电测定业务(Radio Determination Satellite Service,RDSS)系统多波束入站的特点,通过实时测量RDSS系统2个波束入站干信比,同时参考RDSS卫星G/T值差值分布情况,提出一种RDSS系统幅差法入站干扰源定位方法。基于该方法给出了干扰参数获取、参考数据库建立以及多值点排除等关键技术的实现途径,以及干扰源定位试验结果。试验结果表明:该方法对于地面干扰源,相比其他干扰源定位方法,具有定位速度快的显著特点,可作为RDSS系统入站干扰源定位的一种有效手段。
According to the multiple-beam characteristic of RDSS system, a quick interference location method based on amplitude difference method is proposed, by measuring in real time the interference-to-signal ratio from multiple beams and analyzing G/T value difference distribution of RDSS satellite. The implementation of key technologies such as interference parameter acquisition, reference database foundation and multiple value points exclusion are presented in detail,and the interference source location test results are given. The test results show that the proposed method is effective,and can provide the RDSS system with a solution of interference source location.
