Embodiment 1

[0065] like figure 1 As shown, the general UUV underwater target detection process mainly includes: parameter binding, active and passive switch control, independent detection and reporting and other basic processes. From the perspective of simulation operation, the process of UUV underwater acoustic detection is sorted out, mainly to clarify the working logic of active sonar and passive sonar, and to carry out active and passive detection reasonably according to the control requirements of the platform.

[0066] (1) Parameter binding

[0067] In the initial stage, the general model of UUV underwater acoustic detection is bound with initialization parameters, and the initial information of the target, the initial information of the UUV platform, the initial information of sonar detection, etc. are bound through external modules, and the environmental information is loaded at the same time.

[0068] (2) Boot control

[0069] The UUV platform gives an active work instruction, ...

Embodiment 2

[0167] Embodiment 2 of the present invention provides a kind of general UUV underwater target detection simulation system, described system comprises: detection mode selection module, active detection module and passive detection module;

[0168] The detection mode selection module is used to receive the selected detection mode; the detection mode includes: active detection and passive detection; if active detection is selected, the active detection module is turned on to obtain the target detection result; otherwise, the passive detection is turned on module to obtain target detection results;

[0169] The active detection module is used to transmit active detection signals, calculate the active detection propagation loss value based on the sound field analysis; calculate the active detection quality factor based on the active sonar equation; judge whether the target is detecting according to the active detection propagation loss value and the active detection quality factor ...
