Improved Algorithm for Ground-wave Attenuation Factor Prediction over Irregular Terrain and Results Consistency Study

  • 摘要: 針對低頻地波衰減因子預(yù)測算法中積分方程算法與其它經(jīng)典算法在均勻/分段均勻光滑路徑模型下求解結(jié)果不一致的問題進(jìn)行研究分析。引入球面校正因子和高程轉(zhuǎn)換技術(shù),對積分方程方法進(jìn)行改進(jìn),提高其與其它經(jīng)典算法在光滑路徑模型下預(yù)測結(jié)果的一致性。在此基礎(chǔ)上,將改進(jìn)算法用于實(shí)際不規(guī)則地面模型地波衰減因子預(yù)測,并與實(shí)測結(jié)果進(jìn)行比較。與原算法相比,改進(jìn)后的算法更適合考慮地球曲率影響下復(fù)雜長距離地面及空中地波衰減因子的求解。
