摘要

印度星座导航系统(NavIC)是印度的全球导航系统，运行在l波段和s波段。本文对NavIC接收机接收到的直接路径信号和土壤表面反射信号进行了研究。我们分析了这种多径信号对土壤湿度变化的影响。观察到，土壤表面反射的信号反映了土壤湿度。在较低入射角(13°-30°)下观察到多径信号可以将反射信号与直接信号隔离开来。应用最小二乘正弦拟合来确定分离信号的幅度。观测到的土壤湿度与反射信号的幅值有很好的相关性。

Sensitivity of NavIC signal for soil moisture variation

Navigation with Indian Constellation (NavIC) is Indian's Global Navigation System which operates at L-band and S-band. In this paper, we have studied the signal received by NavIC receiver by direct path as well as the reflected signal from the soil surface. We have analyzed this multipath signal for the variation of soil moisture. It is observed that the reflected signal from soil surface is indicative of soil moisture. The multipath signal at a lower incident angle (13°–30°) was observed to segregate the reflected signal from direct signal. The least square sinusoidal fit was applied to determine the amplitude of the segregated signal. A good correlation was observed between the observed soil moisture and amplitude of the reflected signal.
