【摘要】：针对当前航天测控系统安全性不足的问题,将脉冲超宽带技术应用于航天测控系统中,构建了一种新的脉冲超宽带测控体制。建立了基本的脉冲超宽带测控信号模型,对脉冲超宽带测控系统的性能和传输链路进行了分析。给出了脉冲超宽带测控系统结构框图,介绍了系统工作过程。针对并行信号捕获方法资源消耗大的不足,提出了两步并行捕获方法。分析表明,脉冲超宽带技术可用于航天测控系统中,完成测距测速和数据传输任务。脉冲超宽带测控系统可有效提高测控系统的隐蔽性和抗干扰能力,同时提高测距精度。在信号捕获方面,与并行捕获方法相比,两步并行捕获方法的硬件资源消耗得到大大降低,同时还可保证较快的捕获速度,但会产生一定的信噪比损失。
[Abstract]:In view of the current shortage of space measurement and control system of security problems, the pulse ultra wideband technology used in aerospace measurement and control system, and proposes a new UWB control system. The establishment of ultra wideband signal and the basic model of pulse to pulse ultra wideband system performance and transmission link are analyzed is given. The structure diagram of the ultra wideband pulse control system, introduces the working process of the system. According to the parallel signal acquisition method of large consumption of resources shortage, puts forward two steps parallel acquisition method. Analysis shows that pulse UWB technology can be used in aerospace measurement and control system, and complete the task of data transmission. The range and velocity measurement and control system can effectively improve the concealment and anti interference ability of ultra wideband pulse measurement and control system, and improve the measurement precision. In signal acquisition, compared with parallel acquisition method, hardware resources two step parallel acquisition method The source consumption is greatly reduced and the fast capture speed can be guaranteed, but a certain loss of signal to noise ratio will be produced.
