潜艇声呐的功能仿真

Function Simulation of Submarine Sonar

潜艇首部声呐平台区结构复杂，激励也是随机和宽带的，其中，高频（500Hz~10kHz）自噪声预报通常采用SEA（统计能量分析）。

The structure of submarine sonar platform area is complicated and the driven forces are random and wide-band . Statistical energy analysis is often used to predict its middle and high-frequency ( 500Hz ~ 10kHz ) .

潜艇首部声呐平台区低频自噪声预报方法

Prediction method for low frequency of self-noise in submarine 's fore-body sonar platform area

低频操声干净器主要用于对抗控制线导鱼雷的潜艇平台声呐。

Low frequency noise-jammers are used to rival the active and passive sonar of submarines with line-guided torpedoes .

采用经验公式计算各子系统模态密度，最后利用统计能量法来预报潜艇首部声呐平台区自噪声，得到了令人满意的结果。

The subsystems ′ mode density is calculated by empirical formulas . Finally , SEA is adopted to predict self-noise in sonar platform area and satisfying results are obtained .
