摘要
新型陆基无线电导航系统企图继承以GPS为代表的星基无线电导航系统的若干技术成果,特别是伪噪声相位编码扩频技术,以便大大提高以罗兰C为代表的经典陆基无线电导航系统的定位精度。但是,不可避免的遇到几个技术难题,包括无线电传播速度变化的影响,天波干扰问题,以及远近效应问题。分析这些因素的作用机理,通过典型实例定量的评估这些影响,并给出了解决这些技术难题的途径。
New type onshore radio navigation system has a high precision of location, using production of satellitic radio navigation system similar to GPS. especially pseudo random phasic coding technique. Inevitably, some technically difficult problem must be solved, including the variety of speed about tropospheric propagation, the sky wave disturbance and the near-far problem. Analyzing the theory of these factors, quantificationally numeration is provided. Finally, the approach of the difficult problems will be given.
