Zusammenfassung:The invention provides a burst signal capturing method and device, electronic equipment and a storage medium, and the method comprises the steps: carrying out the preprocessing of a received baseband signal, and determining a first target baseband signal meeting a preset bit width demand; converting the first target baseband signal into two paths of second target baseband signals with a difference of half a symbol period for time domain acquisition, and determining a first initial position of a burst frame signal in the first target baseband signal; and determining a plurality of sampling point positions in the first target baseband signal by taking the first initial position as a center, and performing frequency domain search on the plurality of sampling point positions to determine a capture result of the burst frame signal in the first target baseband signal. According to the method, the anti-frequency-offset effect can be achieved in a time domain coarse capture and frequency domain fine search mode, the
