摘要
The channel model has been established by analyzing the characteristics of the non-line-of-sight environment in a domestic airport surface and referencing mobile communication and air channel research. Through estimating the channel multipath time delay and deducing the analytical formula of Doppler spectrum that incident angle in Gaussian distribution, we got the spread of frequency that produced by relative motion and we describe the relevance of the established channel by contrasting the actual value and theoretical value of the channel correlation coefficient. Channel evaluation also by analyzing channel capacity in different antenna configuration to compare priori knowledge. The simulation results show that the established channel model can accurately describe the characteristics of the non-line-of-sight environment in the airport surface and it can be used for the design of multilateration (MLAT) system and the research of Time Difference of Arrival (TDOA) localization algorithm.
