Method and apparatus for positioning with wireless signals

The invention discloses a method and apparatus for positioning with wireless signals. In the method, one or more target receivers and one or more reference receivers are configured to receive a plurality of signals transmitted at an unknown time from a plurality of sources located at an unknown position and asynchronous with each other. The method comprises obtaining arrival times of the pluralityof signals at the one or more target receivers; obtaining a plurality of arrival times of the plurality of signals at the one or more reference receivers from the one or more reference receivers; anddetermining a location of the one or more target receivers by calculating based on the plurality of arrival times at the respective one or more reference receivers, the plurality of reference locations, and the arrival times at the one or more target receivers. 公开了一种利用无线信号进行定位的方法和设备。在该方法中，一个或更多个目标接收机和一个或更多个参考接收机被配置为接收从位于未知位置并且彼此不同步的多个源在未知时间发送的多个信号，该方法包括：获得多个信号在一个或更多个目标接收机处的到达时间；从一个或更多个参考接收机获得多个信号在一个或更多个参考接收机处的多个到达时间；以及通过基
