测量系统采用了微波信号源、低噪声放大器和微波检波器等组成微波电路单元。

The microwave circuit unit is composed of microwave signal resource, low noise amplifier and microwave detector.

目前在野外采集过程中通过检波器组合压制抽油机噪声是最好的解决方法。

Now the best method to attenuate pumping noise is the 3-d vector combination of geophones in field acquisition.

采集时可以用震源及检波器的组合，使噪声达到最小；在处理时，可以用滤波和数据叠加使噪声最小。

Noise can be minimized by using source and receiver arrays, generating minimal noise during acquisition and by filtering and stacking data during processing.
