The Grid-based Simulation for Power Synthesis of Sparse Array Coherent Signal

稀疏阵列相干信号功率合成栅基仿真技术包括阵列功率合成数学建模、栅格尺度原则选定及计算机仿真实验设计实现等。文中从多点源稀疏阵列交汇区域相干信号的功率合成原理出发,建立其数学模型,设计了栅基实验流程,并对实验中重要参数栅格尺度的选定原则进行了推算分析,为利用计算机无失真地复现多点源功率合成能量分布规律打下了理论基础。

The grid-based simulation for power synthesis of sparse array includes power synthesis modeling, the sampling interval setting and realization of the computer simulation experiments. Based on the principle of power synthesis of sparse array, the mathematical model is established and the grid-based simulation experiment is designed. The setting principle of the most important parameter-sampling interval is analyzed. The results could be the theoretical basis for the further analysis of the space power synthesis of multi-source sparse array.
