传统的回波建模方法是采用单亮点模型,仿真出的回波与真实潜艇回波往往有较大差别。针对单亮点模型的不足,本文采用多亮点模型来实现潜艇回波仿真,构造了一个6亮点的回波模型。从仿真结果看,它与单亮点回波模型相比,能更充分地体现潜艇这一扩展目标所造成的回波脉宽延伸和幅度起伏特性,并与实际潜艇回波相吻合。
Traditional echo modeling method is to use a single bright spot model, the simulation of the echo and the real submarine echo often have a big difference. Aiming at the shortcomings of the single bright spot model, the multi-bright spot model is used to realize the submarine echo simulation, and a 6 bright spot echo model is constructed. From the simulation results, it can more fully reflect the echo pulse width extension and amplitude fluctuation caused by this submarine expansion target, which is consistent with the actual submarine echo compared with the single bright spot echo model.
