摘要
研究舰船在动态条件下的散射特性对于目标识别而言具有重要的价值。以"提康德罗加"级巡洋舰为例,首先简要介绍了舰船静态散射特性数据的获取方法,其次以切片理论为核心建立了完整的水动力学模型,进而对舰船的动态散射回波进行了仿真。最后对仿真数据进行了统计分析,获取了舰船在不同海况、不同入射余角条件下的回波稳定性估计,并通过与外场实测数据的比较间接验证了模型的可信性。研究结果可为海面雷达目标识别提供一定的理论支撑。
The scattering characteristics of ship under dynamic conditions are of great value for target recognition. Taking Ticonderoga-class cruiser for an example,the method of obtaining static scattering characteristics data of ship is briefly introduced at first. Then,the whole hydrodynamic model is built based on strip theory,and next the simulation of the dynamic scattering echo of ship is carried out. Finally,the estimation of echo stability under different sea states and grazing angles is achieved through statistically analyzing the simulation data,and its credibility is indirectly demonstrated by comparing with the field collected data. The research results could offer some theoretical support for sea surface radar target recognition.
