【摘要】：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]:The performance analysis of irradiation source is an important problem in the field of external radiator radar. Aiming at a kind of non-orthogonal multi-carrier modulation signal, FBMC signal, the performance of radiation source used in multistatic radar is analyzed. The closed expression of spatial incoherent multistatic average fuzzy function based on FBMC signal is derived. on this basis, the range resolution performance of multistatic radar system under four different radar stations is analyzed by taking the projection area of fuzzy function-3 and dB as the index. The simulation results show that increasing the number of radar transmitting stations and receiving stations can improve the range resolution ability of the system, and under the condition of a certain number of transmitting stations and receiving stations, changing the deployment of transmitting stations will obviously change the range resolution performance.
