With the serial and synthetical development of sonar equipments , the development of signal simulator takes on the trend of standardization universalizalion and digitalization 隨著聲納設備研制的系列化、綜合化,聲納信號模擬器的發(fā)展呈標準化、通用化、數字化的趨勢。
In order to control sound radiation from a baffle in sonar equipment excited by vibration and noise from a ship , the baffle was modeled as a simply supported rectangular thin plate and its radiation characteristics were analytically investigated 摘要為抑制聲吶設備中障板受艦船振動、噪聲激勵而產生的聲輻射,將障板轉化成簡支薄板模型,分析其在諧波激勵下的聲輻射。
Evaluation was conducted at the basic point of efficiency of observational system , and expressed by probability of intercepting and capturing target by sonar equipment of submarine , which provided scientific foundation for organizing and commanding of missile attack about submarine 具體指示效能評估在觀察系統(tǒng)效能評估的層面上進行,用水聲設備截獲被打擊目標的概率來表示,為保障潛艇導彈攻擊目標指示組織指揮提供了科學的依據。
