Abstract

The invention discloses a signal angle and signal frequency estimation method and device, equipment and a storage medium. The signal angle and signal frequency estimation method comprises the steps of: collecting the initial data of a satellite signal through an antenna array element; substituting the initial data into a signal function, and solving to obtain a satellite signal; and acquiring the angle and frequency of the satellite signal according to the satellite signal. In a non-Gaussian noise environment, the angle and frequency of the satellite signal are jointly estimated by considering the space domain sparse characteristics and frequency domain sparse characteristics of the satellite signal at the same time, so that a satellite navigation receiver can capture and track the satellite signal subsequently.

Description

technical field [0001] The invention relates to the field of satellite signal processing, in particular to a method, device, equipment and storage medium for estimating signal angle and signal frequency. Background technique [0002] Research on satellite signal angle estimation or satellite signal frequency estimation is usually carried out under the background of Gaussian noise. However, in the work of satellite navigation receivers, non-Gaussian noise, such as impulse noise, inevitably occurs, and there is still a lack of estimating the angle and frequency of satellite signals under the background of non-Gaussian noise. Contents of the invention [0003] The main purpose of the present invention is to propose a method, device, device and computer-readable storage medium for estimating signal angle and signal frequency, aiming to provide a method for estimating the angle and frequency of satellite signals in the background of non-Gaussian noise. The estimation method of...
