Low resolution and low signal noise ratio are big obstacles in the way of increasing the accuracy and level of deep strata exploration.

深层地震反射资料分辨率、信噪比低是制约进一步提高深层勘探精度，加大深层勘探力度的重要因素。

Raw thermal images acquired by pulsed thermography(PT) usually have low signal noise ratio(SNR) and temperature contrast.

脉冲热像检测中直接获取的原始热像往往信噪比较低、对比度较差。
