它可應用於任何復雜的傳播環境中，能找到發射機到接收機之間的所有電波傳播路徑而無須冗餘的計算，是一種準三維的預測模型；另外，從本質上講，它仍然是一種基於鏡像理論的點對點的射線跟蹤法，所以它無須進行接收測試；而且由於採用了反向演算法，運用數據結構中多叉樹的概念，先確定需要計算的場點位置，找出所有能從源點到達場點的射線，並且可一次性建立一個虛擬源樹，以後每次的計算只要通過對該樹進行後序遍歷即可，大大提高了運算速度，因而有較高的接收效率與精度。本文對該模型進行了相應的模擬，並將其預測結果與實測結果以及基於cost231經驗性模型和基於強力射線跟蹤確定性模型的預測結果進行了比較，結果表明了該模型的優越性。 -
