中文摘要:
      模拟多波束系统,仿真得到了水下目标的二维回波亮点声图像。先采用小分置角双基地目标回波特性计算的近场板块元方法,计算得到水下目标的传递函数。再根据多波束系统的理论,建立了水下目标回波亮点二维声图像的基本框架,实现了水下目标回波亮点二维声图像仿真。最后得到了水下目标不同方位角情况下近程二维回波亮点的声图像。
英文摘要:
      A two-dimensional bright spot image of an underwater target is obtained by simulating a multi-beam system.The transfer function of underwater target is calculated using the near-field planar element method of small bistatic angle and bistatic echo characteristics.Based on the theory of multi-beam system,a basic frame of 2D image of bright spots of underwater target is built,and simulation performed.Near-field 2D acoustic images of bright spots of underwater target under different azimuth angles are obtained.
