Two or more scaled SAR results of the same variety—either raw SAR sensor data or SAR averages—can be summed to find a maximum combined SAR value.
Combine SAR results by following these steps:
- Use Ctrl+ to select two or more similar results in the Results browser, such as two 1-gram SAR averages.
- Right-click and select Combine SAR Results
This option produces a dialog containing a table of the selected SAR results.
- Choose the Frequency of each result.
- Specify the scaling factor for each result by editing the Net Input Power or Max SAR value.
- Click OK to begin the computation.
A workspace window displays the result of the computation, giving the maximum combined SAR value and a list of one or more cell locations where that maximum was found. The grid indices of the cell are also provided in the list across the bottom.
In the example above, the calculation grids were identical for the two input runs. When they are not identical, a grid location is provided for each input run and a message noting that identical grids were not used will also be displayed in the lower-left corner. In such a case, each input distribution's SAR value per cell is considered constant for that run. When cells from different runs are partially overlapping, the SAR value of each covered cell portion of one grid is combined with the SAR value of each overlapping cell of the other grid. In other words, the SAR values of all cell portions that the grids have in common are summed.
Users should note that unlike SAR averaging and far zone post-processing, SAR combination results are not saved to disk, and therefore must be recomputed each time they are requested. Once computed, a combined SAR result does not respond to scaling changes to its constituent parts.
