使用支持向量机进行目标弹道的识别，并应用于雷达弹道外推-support vector machine is paalied to recognize trajectories. then it is employed to model the trajectory data.

Abstract—Several algorithms have been developed for tracking formant frequency trajectories of speech signals, however most of these algorithms are either not robust in real-life noise environments or are not suitable for real-time implementati
