2 . the idea and method to velocity - zeroize artifical accelerations is put forward 2 、提出了對人工合成地震動進行速度歸零化的觀點和方法。
At the same time , at the aspect of theory , we give a lot of results , including : performance calculating formula of fft phase comparing , coincidence relation of calculating result and target " s real range , calculating formula under zeroize fft or single channel 在相關理論上,我們提出了fft比相的性能指標計算公式、 fft比相下測距結果與目標實際位置之間的對應關系、補零和單通道下的fft比相結果。
