Abstract
The application discloses a multi-target detection method and device, equipment and a storage medium, and relates to the technical field of data processing. The method comprises the following steps: generating a current range-Doppler information matrix according to a receiving signal of a detection device; determining a current time-frequency signal according to the current range-Doppler information matrix, and determining detection information of a first target object; orthogonally projecting the receiving signal on the current time-frequency signal, and generating a target range-Doppler information matrix according to a target signal orthogonal to the current time-frequency signal; and determining detection information of a second target object according to the target range-Doppler information matrix. In the foregoing manner, after the detection information of the first target object is obtained, the receiving signal is orthogonally projected on the current time-frequency signal, and the detection information of other target objects is determined according to the orthogonal target signal, so that the detection of the multi-target objects can be realized, the multi-target detection capability in a multipath environment can be improved, and the dependence on hardware can be reduced.
