Abstract应用作用量守恒理论,对二维作用量谱平衡方程的波流作用机理及源(汇)函数进行分析,并对水下运动源内波尾迹在自由面(水面)形成的辐聚和辐射流场引起的作用量谱扰动进行了数值仿真,模拟出不同的配置条件下作用量谱扰动可能存在的"不对称性"。根据海面微波散射及雷达海面成像理论及作用量谱扰动的数值仿真结果,认为内波尾迹雷达散射的不对称可能是源自于作用量谱扰动的"不对称性"。
Other AbstractAn analysis of 2-D wave-action spectrum balance equation and its source-sink function,which describing the mechanism of wave-current interaction,is presented.By using this mechanism,the perturbation of surface action spectrum caused by internal-wave wake due to underwater moving object is numerically simulated,and the possible phenomena of 2-D asymmetry of spectrum perturbation for the various configurations is shown.According to the radar imaging of microwave scattering theory and the action spectrum of perturbation simulation results,it is suggested that waves wake asymmetry on the radar imaging data may be derived from the asymmetry of the action spectrum perturbation.
