全空间杂波功率计算方法

摘要

针对空中平台侦察过程中受到杂波影响的问题,提出了全空间杂波功率计算方法.该方法将杂波功率计算从单散射块的简单模型扩展到全向散射空间的精确模型,在等距离环内推导出杂波功率数学表达式.仿真实验结果表明,杂波对提取纯净信号有较大影响,杂波多普勒距离相关.%In view of the impact of clutter on the aerial platform,this paper proposed a whole space calculation method of clutter power.Calculation of clutter power was extended to the accurate model of the omnidirectional scattering space from the simple model of the single scattering block.The mathematical expression of clutter power was derived from the equal-distance ring.The simulation results showed that the clutter had a great influence on the extraction of pure signals,and the clutter Doppler frequency was related to the distance.
