| description | The invention discloses a TOAs/FOAs closed-type cooperative positioning method under the condition that a time-frequency synchronization error exists in a sensor at a transmitting end and a sensor at a receiving end, and provides a TOAs/FOAs cooperative positioning mode facing multiple radiation sources for a positioning scene that the sensor at the transmitting end and the sensor at the receiving end have the time-frequency synchronization error. Closed-form solutions of multi-radiation-source position parameters, multi-radiation-source speed parameters, time domain synchronization error parameters and frequency domain synchronization error parameters can be given at the same time. The method has relatively high calculation efficiency, not only can effectively suppress the influence of time-frequency synchronization errors of the sensors at the transmitting end and the receiving end, but also can obtain relatively high cooperative gain.
