與噴氣式飛機和螺旋槳飛機相比，直升機的雷達回波具有不同的特點。 -
Under the bow the water was hissing as from a steam jet, the air was filled with driven spray, there was a rush and rumble and long - echoing roar, and the canoe floated on the placid water of the lagoon
船船下海浪嘶嘶地怒吼著有如噴著水氣的噴頭，空氣里彌漫著飛濺的浪花，沖擊奔騰的喧嘩聲此起彼伏，然後，獨木船便已漂浮在礁湖裡平靜的水面上。 -
This paper studies the helicopter, the propeller - driven aircraft and the turbofan jet airplane echo modulating feature parameter model and analyses the echo signal feature. it gains the target echo ’ s the cyclical modulation feature by using the complex ar frequency range bispectrum slice. because traditional method in extraction airborne radar ’ s radiant signal feature time has certain insufficiency, this paper proposes the approximate entropy and the norm entropy as the passive feature parameter in the airplane
由於傳統方法等在提取機載雷達輻射源信號特徵的時候存在著一定的不足，本文提出把近似熵和范數熵作為飛機目標識別的無源特徵參數，給出了提取相應特徵熵的演算法，實現對機載雷達輻射源信號的識別，通過和機載雷達類型的匹配，實現對目標的識別。 -
Because of the jet flow field for the prestage of hydraulic servo valve driven by jet flow, it is difficult to build an accurate mathematical model, thereby the analysis of servo pipe and whole servo control system is difficult to be carried out
由射流前置級驅動的伺服閥，由於射流流場的不確定性及流場分佈的復雜性，因而很難建立精確的數學模型，從而使伺服閥及整個伺服控制系統的分析難以實現。 -
