摘要
由于具有隐蔽性好、抗干扰能力强、系统可靠简单等优点,基于外辐射源的无源雷达近年来受到国内外的重视,成为研究热点。本文论述了基于GPS的无源雷达系统优势,以及基于系统的几何构型和未来发展能力的GPS信号的探测距离。分析了GPS信号的双基地模糊函数,并给出仿真结果。研究表明,基于GPS信号的无源雷达具有广阔的发展前景。
In recent years, the passive radar based on the external radiator has received domestic and international attention and becomes a research focus due to its advantages such as good concealment performance, strong anti jamming capability, high reliability and simple structure. The advantages of the passive radar based on the GPS signals are discussed, and the detection range of the GPS signals is analyzed based on the geometric configuration and the future development ability of the system. Besides, the bistatic ambiguity function of the GPS signals is analyzed with the simulation results given. Tile study shows that the passive radar based on the GPS signals has broad development prospects.
