Multi-target position classification wireless sensing method, device, and medium

A multi-target position classification wireless sensing method, comprising:

• determining a channel impulse response of each antenna oscillator in a multi-antenna array in receiving a sensing signal;
• calculating a delay-angle of arrival spectrum according to the channel impulse response of each antenna oscillator in receiving the sensing signal;
• dividing and classifying a path distribution area according to the delay-angle of arrival spectrum;
• in presence of a separable path in the path distribution area, taking an angle corresponding to a maximum amplitude point in an ambiguity range of the separable path as an angle of arrival of the separable path, and taking time corresponding to the maximum amplitude point in the ambiguity range of the separable path as time of arrival of the separable path;
• and
• in presence of an inseparable path in the path distribution area, according to an angle ambiguity range and a delay ambiguity range of a graph comprising the inseparable paths, estimating an angle of arrival and time of arrival of each inseparable path in the graph of the inseparable paths.
