摘要
首先结合水面舰船目标的特点和非相干叠加理论,设计了舰船目标一维距离像建模计算的具体流程;然后对某型实际舰船目标建立了基于基本散射形状的几何模型,给出了目标模型可见面判定的基本方法,提取了目标模型用于电磁计算的几何信息;最后利用宽带高分辨雷达目标一维距离像模型,并在考虑海浪波动、海面镜像影响的条件下,对所建几何模型进行了一维距离像的仿真计算。计算结果验证了所提出方法的有效性。
The flow of the ship target's high range resolution profile(HRRP) modeling and computation is designed based on the characteristic of the sea surface ships and the incoherent theory.Then take a real ship target as an example,the geometry model based on the basic electromagnetic scatter shape is established,and the target parameters for electromagnetic calculation are acquired based on the model partition,approximation and visual surface determinant.Last,according to the HRRP model based on linear frequency modulation(LFM) signal,the HRRP of the geometry model with the influence of sea surface and offing image is calculated.Calculation results prove the validity of the method proposed.
