Emissionsermittlung aus Meßergebnissen

Aus Meßergebnissen für Aufpunkte kann auf die Höhe der Emission von unzugänglichen Quellen geschlossen werden, deren Lage bekannt ist.

In diesem Rückrechnungsverfahren werden u.a. berücksichtigt:


Concluding on source intensity from measured noise levels

Calculating Source Intensity

When the source intensity can only be analysed indirectly from greater distance LIMA offers the opportunity to calculate the source intensity. The algorithm can deal with numerous unknown sources simultaneously. Fixed relative relations between these sources may be defined. Background noise and any effects of the propagation are taken into account when the source intensities are calculated, trying to minimise the variance to the measured values at the locations of the measurements.

The colours of picture A represent the assumed intensity of the unknown sources. Picture B shows the calculated source intensities.
