Abstract
A signal angle and signal frequency estimation method, apparatus, device and storage medium are provided. The signal angle and signal frequency estimation method comprises the steps: collecting initial data of a satellite signal by means of an antenna array element; substituting initial data into a signal function, and finding a solution to obtain the satellite signal; and obtaining the angel and frequency of the satellite signal according to the satellite signal. According to the method, in consideration of the non-Gaussian noise environment as well as spatial domain sparse feature and frequency domain sparse feature of the satellite signal, the angle and the frequency of the satellite signal are estimated jointly, thereby facilitating subsequent obtaining and tracking the satellite signal by a satellite navigation receiver.
