Pulse Building
Antenna Pattern Type sets the pattern type for the antenna scan. Each type has specific properties that control its behavior. Changing the antenna pattern type causes the scan properties to be reset to their default values.
Available antenna scan pattern types are:
| Antenna Pattern Type | Description | Visual Configuration |
| None | No antenna scan modulation is applied to the pulse pattern. | |
| Circular |
The antenna beam rotates in a circular motion. The following property is used with this Type: Scan Rate |
|
| Conical |
The antenna beam rotates in a cone-shaped pattern. The following properties are used with this Type:
|
|
| Custom |
A custom amplitude pattern is provided by importing a file containing amplitude data. The file format is ASCII CSV and the data is assumed to be in dB. The valid data range is from -100 dB to 0 dB. Time is assumed to be constant and equal between data points. It is assumed that the file contains one complete scan of the amplitude pattern. The time increment between data points is established using the scan rate property. The Custom amplitude pattern is not combined with any other antenna properties except Null Depth. The maximum dynamic range of the amplitude pattern is hardware specific and most likely less than 100 dB. The following properties are used with this Type:
The following properties are not available for this Type:

| Bidirectional Raster |
The antenna beam sweeps back and forth across a raster grid. The following properties are used with this Type:
|
|
| Unidirectional Raster |
The antenna beam sweeps in one direction across a raster grid, then returns to the start. The following properties are used with this Type:
|
|
| Bidirectional Sector |
The antenna beam sweeps back and forth within a defined sector angle. The following properties are used with this Type:
|
|
| Unidirectional Sector |
The antenna beam sweeps in one direction within a sector, then returns without scanning. The following properties are used with this Type:
