摘要

基于骨架结构元（骨元）技术，提出一种灵活高效的电磁散射宽角度扫描算法.与已有骨元扫角算法不同，本文提出的算法对扫描角度抽样没有任何限制.算法将所有角度抽样对应的右端项向量空间用一组骨元向量来表达，通过求解一个超定方程得到任意角度抽样对应的右端项向量.对超定方程的求解进行了分析，研究了超定方程的求解精度与开销问题.讨论了超定方程引入对骨元扫角的影响.通过超低散射目标和电大复杂目标的雷达散射截面数值仿真结果，验证了所提算法的精确性和高效性.

Abstract

Based on previously developed angular sweeping grounding on skeletonization

a flexible and efficient wide angular sweeping algorithm is proposed. Different from the previous skeletonization-based angular sweeping methods

the proposed one removes the limitation on how to select the incident samples. Taking the skeleton right-hand sides(RHSs) as the basis vectors which can uniquely and accurately represent the vector space of the whole RHS space

the RHS of an arbitrary incident can be obtained by solving an overdetermined system. The accuracy and the cost of solving the overdetermined system is analyzed. The impact of the overdetermined system on the angular sweeping is discussed. Numerical experiments are carried out to show the performance of the proposed method to solve the overdetermined system. Radar cross section(RCS) computations on ultra-low scattering targets and electrically large complex targets validate the performance of the proposed angular sweeping algorithm.
