Embodiment Construction
[0055] The present invention will be further described now in conjunction with accompanying drawing.
[0056] Before describing the non-cooperative target trajectory tracking method under the multi-observation node condition of the present invention, firstly, a brief description will be given to the scene to which the method of the present invention is applied.
[0057] There are multiple signal transmitting points and multiple observation receiving points deployed in the ocean, and all signal transmitting points and all observation receiving points are time-synchronized. The signal transmitting point periodically transmits a pulse signal, and the observation receiving point receives the target echo and direct wave signal, and at the same time, the observation receiving point also realizes signal direction finding.
[0058] Under this working condition, the non-cooperative target trajectory tracking method under the multi-observation node condition of the present invention com...
