| 摘 要： | 外辐射源雷达常用的调频广播、全球移动通信系统(GSM)等窄带信号照射源都具有较低的距离分辨率及多普勒分辨率。针对这一问题,提出了一种以宽带LTE(长期演进系统)信号作为照射源的浮空平台外辐射源雷达体制。阐述了该种体制雷达的目标探测原理,分析了LTE 信号生成机理以及该信号的距离分辨率、速度分辨率、模糊函数及探测威力。计算机仿真表明,利用LTE 信号能够成功实现目标探测。

| Abstract: | Low range and velocity resolution is frequently encountered in the airship borne passive bistatic radar based on frequency modulated radio, global system for mobile communication and other narrowband signals. Aiming at the above situation, an airship borne passive bistatic radar system utilizing long term evolution(LTE) signal is proposed. The target detection methodology is described. And the method of LTE signal generation, range resolution, Doppler and velocity resolution, ambiguity function and coverage are analyzed. Computer simulations show that the airship borne passive bistatic radar based on LTE signal could accomplish the target detection task successfully. |
