Title:
ECHO SIGNAL INTERFERENCE DETERMINATION METHOD AND APPARATUS, ELECTRONIC DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/100482
Kind Code:
A1
Abstract:
An echo signal interference determination method and apparatus, an electronic device and a storage medium. The echo signal interference determination method comprises: performing binarization processing on an echo signal, to generate first pre-processed data (101); according to at least one frequency repetition interval of the echo signal, acquiring at least one piece of binarization processed second pre-processed data corresponding to the at least one frequency repetition interval (102); selecting any two pieces of pre-processed data from the first pre-processed data and the at least one piece of second pre-processed data, and performing a logic operation on the selected two pieces of pre-processed data, so as to obtain a logic operation result (103); determining a detection waveform range on the basis of the echo signal corresponding to the selected two pieces of pre-processed data, and performing an accumulation operation on the logic operation result within a time period corresponding to the waveform range (104); and when it is determined that the accumulation operation result is greater than a first set threshold, determining that the echo signal corresponding to the selected two pieces of pre-processed data is interfered with (105).
