Detection method of solar radio bursts based on decrease of GPS carrier-to-noise ratio.

Taking advantage of the influence of solar radio bursts on the performance of global positioning system (GPS), a detection method of solar radio bursts based on the decrease of GPS carrier-to-noise ratio is proposed. Firstly, the solar incidence angle of the observation ground is calculated, then the "falling points" and "rising points" are selected to determine the time interval of the trough of a single satellite from the single observation ground, and finally the detection results of the solar radio bursts are determined by integrating multiple satellites and multiple observation grounds. The experimental results show that the detection rate of solar radio bursts increases with the increase of the solar incidence angle, the detection rate of solar radio bursts above 600 SFU on the L2 frequency band reaches more than 80%, and the detection effect on the L2 frequency band is better than that on L1. This detection method has a high recognition rate, low cost, does not depend on the radio telescope, and can carry out all-weather real-time monitoring. [ABSTRACT FROM AUTHOR]
