脉冲超宽带信号应用于测控领域的可行性研究

脉冲超宽带通信是指利用脉宽为纳秒级的脉冲作为载体的无线通信技术，将脉冲超宽带信号应用于测控领域，能有效提高当前测控系统的隐蔽性、抗干扰性和抗截获性。根据链路预算，脉冲超宽带测控信号到达地面的功率谱密度非常低，不会对地面上的其他系统造成干扰。利用对数正态阴影衰落路径损耗模型，求得脉冲超宽带信号传输距离与信息速率的关系，证明在保证一定信息速率的前提下，脉冲超宽带测控信号能够实现远距离传输。

Feasibility Study of Impulse Radio-Ultra Wideband Signal on TT & C System

Impulse radio-ultra wideband refers to the wireless communication technology used pulse width for nanosecond pulse as the carrier. The application of impulse radio-ultra wideband signal on TT&C field can greatly improve the concealment performance,anti-interference performance and intercept resistance performance of the current TT&C system. According to the link budget,pulse power spectral density of IR-UWB TT&C signal to reach the ground is more lower,which will not cause interference to other systems on the ground. By using lognormal shadow fading path loss model, the relationship of UWB signal transmission distance and rate information was obtaind,and on the premise of guarantee information rate, IR-UWB TT&C signal can realize long distance transmission.
