The algorithm completes range migration correction through correcting the linearity Doppler frequencyline. It can avoid one time inserting processing and reduce calculation.
该算法通过对具有线性的多普勒谱线进行校正来完成距离迁移校正，避免了一次插值运算，减少了运算量。

The HMM based multiple frequencyline tracking algorithms of work well under very low SNR, except for a high complexity of computation and for generally unnegligible quantization error.
基于隐马尔可夫模型的多频率线跟踪算法，能在很低的SNR环境下工作，但量化误差较大，和计算量大。

They were expecting to see one certain frequency or one line in the spectrum at this point here.
