through the noncoherent integration of great numbers of data, and by using hough transform the features of signals in low snr ( signal-to-noise-ratio ) can be extracted . therefore, the hough transform may play an important role in the automatic track initiation and the processing of images with low snr environment 通過(guò)大量數(shù)據(jù)的非相干積累,利用hough變換可在低信噪比下提取信號(hào)特征,這在低信噪比自動(dòng)航跡起始以及低信噪比圖像處理中有重要的應(yīng)用價(jià)值。
