However, in respect of a vibration acceleration signal, the signal to noise ratio (SNR) is often so small that the periodic impulse component is submersed in its intense background noises.
通常检测的机械振动加速度信号，由于信噪比太低，即使存在周期性的冲击分量也往往被淹没在强的背景噪声之中。
Comparing with impulse radar, this method can greatly improve the signal to noise ratio (SNR), the convergence speed is quick, and iterative times are less than 10.
与冲激雷达相比，这种方法能显著提高信噪比，并且这个方法的收敛速度快，一般迭代10次以内即达到稳定。
When the expansion ratio becomes larger, both thrust and specific impulse will increase.
适当增大扩张比能提高微喷管的性能。
