摘要 提出一种综合使用多GNSS系统可用导航卫星信号源和基于MIMO信号处理体制的无源多基地雷达系统结构,利用MIMO处理获得的空间分集增益来改善雷达探测性能。分析了系统的可用信号源情况,讨论了系统中前向散射区的确定和目标前向散射RCS的计算问题,在此基础上,对基于GNSS信号的无源MIMO雷达系统的探测性能进行了深入研究并给出了仿真计算结论。 All available navigation satellite signals radiated by several typical GNSS systems are used in a MIMO signal processing framework, which composed a passive multi-static system as to improve detection performance. The available opportunity GNSS illuminating sources are analyzed, and issues on ascertaining of the system＇s forward scattering zone and calculation of target＇s forward scattering RCS are discussed. On this basis, detection performance of the proposed GNSS based passive MIMO radar system is studied in detail and correlative conclusion is put up by simulation and computation.
