SENSOR RECEIVER NULLS AND NULL STEERING |
摘要 |
A method. In one embodiment there is provided a method in which a direction from a sensor position to a noise source is determined. A coordinate rotation is applied to a first set of signal values, wherein each signal value of the first set of signal values is based on an output of a corresponding component of a three-component particle motion sensor at the sensor position. The applying generates a rotated set of signal values. The coordinate rotation comprises a coordinate rotation transforming a first set of coordinate axes to a second set of coordinate axes, wherein the first set of coordinate axes has each coordinate axis aligned with a corresponding component of the three-component particle motion sensor at the sensor position, and the second set of coordinate axes comprises a first axis pointed in a direction opposite the direction from the sensor position to the noise source. |

1. A method comprising:
determining a direction from a sensor position to a noise source; applying a coordinate rotation to a first set of signal values, wherein each signal value of the first set of signal values is based on an output of a corresponding component of a three-component particle motion sensor at the sensor position, the applying generating a rotated set of signal values, wherein the coordinate rotation comprises a coordinate rotation transforming a first set of coordinate axes to a second set of coordinate axes, and wherein:
the first set of coordinate axes has each coordinate axis aligned with a corresponding component of the three-component particle motion sensor at the sensor position; andthe second set of coordinate axes comprises a first axis pointed in a direction opposite the direction from the sensor position to the noise source. |
