Method and apparatus for determining positioning parameter, device and storage medium

A computer device, comprising a memory and a processor, wherein the memory stores a computer program;

• and the processor, when executing the computer program, implements following actions:
• determining Time of Flight (ToF) spectrum data of a positioning signal according to the positioning signal sent via multi-channels by a terminal to be positioned;
• correcting an ideal spatial manifold matrix according to a preset antenna array deviation function, so as to obtain a corrected spatial manifold matrix, wherein each element in the ideal spatial manifold matrix or the corrected spatial manifold matrix represents a response of each array element in an antenna array to the positioning signal in a preset corresponding angle range, and the preset antenna array deviation function represents a deviation between a response of a real antenna array to a signal and a response of an ideal antenna array to the signal;
• and
• determining a positioning parameter of a Line Of Sight (LOS) of the positioning signal according to the ToF spectrum data and the corrected spatial manifold matrix, wherein the LOS is a shortest path from the terminal to be positioned to the antenna array.
