Block VI: Receiver Array

OASS will compute the reverberant field on arbitrary three dimensional arrays. The first line of this block specifies the number of sensors. Then follows the position, type and gain for each sensor in the array. The sensor positions are specified in cartesian coordinates in meters. The types currently implemented are as follows

1.

Hydrophone. Normal stress (negative of pressure in water) in Pa for source level 1 Pa (or Pa for source level 1 Pa).

2.

Geophone. Particle velocity in x-direction (horizontal). Unit is m/s for source level 1 Pa (or m/s for source level 1 Pa).

3.

Geophone. Particle velocity in y-direction (horizontal). Unit is m/s for source level 1 Pa (or m/s for source level 1 Pa).

4.

Geophone. Particle velocity in z-direction (vertical, positive downwards). Unit is m/s for source level 1 Pa (or m/s for source level 1 Pa).

The gain is a calibration factor in dB which is applied to ambient noise and signal on all sensors. Note: OASS v 1.7 does not currently allow for mixed arrays.
