摘　　要：2.4 GHz直序列扩频微波由于其抗干扰能力强、保密性好等优点,在数据通信领域的应用日益增多,而在交管系统中的应用很少,作者通过对2.4 GHz扩频微波线路的余隙、传播损耗及可靠性的计算,论述了其在交管系统中应用的可行性,并在实践中得到了验证。For its resistance to interference and good security, 2.4 GHz spread spectrum radio has increasing applications in the field of data communication, but it is less used in VTS. The thesis studies on the radio is feasible to be applied in VTS by calculating the fade margin, propagation loss and availability of the path, all calculations and results have been verified in the practice.
