Artificial Ambient Noise Test

7 Dec. 2014

This data set was collected on 7 Dec. 2014 by Sherif and Abdullah. The receiver layout is the same as that of the passive data test at the same location, which is described as follow:

288 receivers are used and arranged as follow

· 12 lines, cross-line offset = 10 m

· 24 receiver in each line, inline offset = 5 m

· Additional 24 receivers are placed at line # 6, where the receiver interval is decreased to 2.5 m.

Figure 1: Receivers layout at the test site. The extra 24 receivers added to line 6 is not shown in this figure.

Dara Recording

We start recording at 10:10 am and stop recording at 11:25 am.

Each record has total of 20 s, with time interval of 0.004 ms and around 2 s overlap between each two successive files.

Source

We used a piece of wood attached to a pick-up truck to create the noise; we drove around the array of receivers in a rectangle-shape route during the recording time.

Data

The data are converted into matlab format and seprated into 2 files:

1. The 3D data set. 288 receivers arranged in 24 x 12 matrix, where the inline = 5 m and the cross-line offset = 10 m, get a copy from here

2. The 2 data set. 48 receivers with 2.5 m receiver interval. Receiver # 1 is located toward the west side of the site. Get a copy from here
