Square neighborhood

You can select a target that includes all pixels within a square region that is centered on the cursor position.

To select a square-neighborhood target

In the SAR Polarimetry Target Analysis window, under TargetSelection Mode, click Square neighbor.
On the Size list, click a number.
The value must be an odd integer because the selection includes the pixel under the cursor location. The size must be 3 pixels or greater. The default size is 1.
Click in the Target Selection window.
The selected pixels are displayed in green. The following is an example of the information displayed in the Results box under Numerical Output in the SAR Polarimetry Target Analysis window:
```
