Embodiment Construction
[0106] Specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0107] The single-beacon-based underwater moving target positioning algorithm uses a water moving beacon to locate the underwater moving target; it is used to calibrate the relative distance between the aircraft and the beacon in the area supported by the beacon. The mobile beacon is equipped with a satellite positioning receiver, an underwater acoustic transducer and a synchronous clock system. The location information of the beacon is obtained through the global positioning system, and its location information and clock information are encoded into the underwater acoustic signal. The work of the beacon is to broadcast the underwater acoustic signal. Signal.
[0108] The underwater moving target is equipped with a horizontal attitude sensor, a speed sensor and a vertical azimuth sensor. The horizontal attitude sensor can obtain the pitch angle ...
