1. A one-bit quantization based target tracking method, comprising:
acquiring echo data of each radar node in a multi-radar node system for a target;
performing one-bit quantization on each echo data separately to obtain one-bit data of each radar node;
estimating a distance information of the target relative to each radar node based on the one-bit data of each radar node, and estimating a direction of arrival of signal corresponding to each radar node based on the one-bit data of each radar node;
determining, based on the distance information of the target relative to each radar node and the direction of arrival of signal corresponding to each radar node, a position information of the target relative to each radar node; and
fussing the position information of the target relative to each radar node to obtain a tracking point of the target, and forming a tracking trajectory of the target based on the tracking point.
