The invention discloses a solar radio burst detection method based on a GPS/BDS carrier-to-noise ratio decrease. The method detects, by means of the influence of solar radio bursts on the GPS/BDS carrier-to-noise ratio, the solar radio burst, and accordingly determines whether the solar radio burst occurs. In this process, the solar elevation of an observation site is firstly calculated and data is preprocessed. Then, a falling point and a rising point are selected out to determine the trough time interval of a single satellite at a single observation sit. Finally, a detection result of the solar radio burst is determined in combination with a plurality of satellites and a plurality of observation sites. The detection method does not depend on a radio telescope, has a high recognition rateand low cost, and can perform real-time monitoring around the clock. 本发明公开了一种基于GPS/BDS载噪比下降的太阳射电暴检测方法，该方法利用太阳射电暴对GPS/BDS信号载噪比的影响，对太阳射电暴进行检测，依此判断是否发生太阳射电暴。在此过程中，首先计算观测地的太阳高度角并进行数据预处理，接着筛选出"降点"和"升点"用于确定单个观测地单颗卫星的波谷时间区间，最后综合多颗卫
