Abstract_Chinese:照射源性能分析是外辐射源雷达领域的一个重要问题, 针对一种非正交多载波调制信号即FBMC信号, 分析其用于多基地雷达照射源时的性能．推导了基于FBMC信号的空间非相干多基地平均模糊函数闭式表达式, 在此基础上以模糊函数-3 dB的投影面积为指标, 分析了4种不同的雷达布站情况下多基地雷达系统的距离分辨性能．仿真结果表明, 增加雷达发射站和接收站的数量均可以提高系统的距离分辨能力, 而且在发射站和接收站数量一定的条件下, 改变发射站部署会给距离分辨性能带来明显的改变．.
Abstract_English:Performance analysis of the illuminators of opportunity is a crucial topic in passive radar field. Considering FBMC(filter-bank multi-carrier)，a kind of non-orthogonal multi-carrier modulated signal was used as the illuminators of opportunity for the multistatic passive radar. The closed form of the average ambiguity function of the non-coherent multistatic radar based on FBMC was derived. Besides，-3 dB contour area of ambiguity function was used as a measurement to compare the range resolution performance under four different kinds of the radar station configuration. Simulation results show that increasing the number of transmitters and receivers can enhance the range resolution performance of multistatic radar system. When the number of transmitters and receivers are given，the transmitters’ location will influence the range resolution performance evidently.
