For those biological signals like echo of bat or whale, as well as man - made system signals like radar or sonar signal, the instantaneous frequency of signal component contains important information and could be used for signal model parameters extraction. so that the proper choose of transformed domain and signal characteristic extraction method is of crucial important. the ridge extraction method used for signal characterization was first proposed in the 1990s, it ' s based on the study of the phase of the wavelet ( or other linear ) transform
對于許多實際的信號，如蝙蝠發出的超聲波、鯨魚的叫聲等生物信號，以及雷達、聲吶等人造系統產生的信號而言，信號瞬時頻率的變化規律反映了信號重要的特徵，並且也是信號模型中關鍵的參數，因此選擇合適的變換域提取信號的瞬時頻率信息，並選擇合適的方法對信號進行重建是很重要的問題。 -
First, according to the orthonormal quality and the rational choice of working point of the sonar array three shafts frame, the structure of the models is predigested preliminarily ; secondly, according to the quality indexes and the coupling quality between frames, relatively small quantum is neglected. so the complex non - linear coupling models of the sonar array are predigested farther ; lastly, considering the characteristic of the model coefficient matrix, the methods of the low rank polynomial approach and the error simulation are introduced. so the models are predigested again
首先從聲納基陣框架結構的正交性和工作點的合理選擇出發，使模型的結構得以簡化；其次根據系統性能指標及框架間耦合性強弱，忽略相對小量，對聲納基陣復雜的非線性耦合模型進一步簡化；最後考慮模型系數矩陣的特點，運用低階多項式逼近和誤差模擬的方法，實現了對模型的再次降階簡化處理。 -
