Zusammenfassung:	An embodiment of the invention provides a pulse description word extraction method and device. The method includes: acquiring baseband signal information, subjecting the baseband signal information tosliding-window-based envelope detection to obtain baseband signal envelope information corresponding to the baseband signal information; subjecting the baseband signal information to noise floor estimation to obtain noise floor estimation information corresponding to the baseband signal information; determining first threshold information and second threshold information according to the noise floor estimation information and the baseband signal envelope information; determining pulse signal information according to the baseband signal envelope information, the first threshold information andthe second threshold information; extracting pulse description words according to the pulse signal information, the first threshold information and the second threshold information. The baseband information is subjected to en
