摘要

摘要:
短波鏈路不同傳播模式的多徑時延通常為0.5～2.0 ms，該文研究同一傳播模式的多徑時延，在考慮地磁場影響的情況下，將電離層短波傳播的折射指數(shù)和射線追蹤結(jié)合起來，給出了數(shù)值迭代算法，實現(xiàn)了用數(shù)值方法來描述電離層色散引起的多徑時延，并進(jìn)行了數(shù)值仿真，得出短波寬帶通信的模擬帶寬應(yīng)為48 kHz。

Abstract:
The multipath delay for different propagation mode is 0.5～2.0 ms, and the multipath delay for the same propagation mode is analyzed. Taking into account the earth magnetic field effects, the refractive index of High frequency propagation in ionosphere is combined with ray tracing, and then a new numerical iteration algorithm is given. The multipath delay caused by ionosphere dispersion is analyzed by numerical method, and the simulation is realized. Thus the analogue bandwidth of wideband communication for high frequency should be 48 kHz.
