摘要
将板块元方法应用到鱼雷导引弹道计算中,对运动目标的回声特性进行了研究。用刚性球Rayleigh简正级数解检验了板块元方法对运动目标回声特性的计算,在此基础上把板块元方法应用到鱼雷尾追法、固定提前角法、平行接近法三种导引弹道下复杂Benchmark模型目标回声特性的研究。此方法为研究水下运动目标回声特性提供了重要的理论依据。
The planar elements method has been applied to calculating the echo characteristics of moving target such as the complex Benchmark submarine model in torpedo guidance trajectory. This method is verified by the Rayleigh normal mode solution of rigid sphere. Thus, the method can be used for calculating echo characteristics under the con-ditions as torpedo stern chasing method, torpedo advance angle fixing method and torpedo parallel approaching me-thod. The results provide an important theoretical basis for the echo characteristics study of underwater moving target.
