The Antenna Object
The Antenna object models the properties and behavior of an antenna. Select one or more of the following to model an antenna and impose constraints:
Basic Properties
| Property |
Description |
| Definition
|
Define the characteristics of the antenna. |
| Orientation
|
Specify the orientation of the antenna coordinate frame relative to the coordinate frame of the parent object. |
| Refraction
|
Model atmospheric refraction. |
| Description
|
Record useful information about the antenna. |
2D Graphics Properties
| Property |
Description |
| Contours
|
Define the display of contour lines and antenna patterns. |
| Boresight
|
Define the display of boresight graphics. |
3D Graphics Properties
| Property |
Description |
| Attributes
|
Control the display of contour lines and antenna patterns. |
| Vector
|
Control the display of vectors and other geometric elements related to the antenna. |
Constraints
| Property |
Description |
| Basic
|
Impose minimum elevation and line-of-sight constraints on access from the antenna to another object. |
| Sun
|
Impose a variety of access constraints from the antenna to another object based on the position of the Sun and the Moon. |
| Temporal
|
Impose time-based access constraints from an antenna to another object. |
| Zones
|
Use inclusion and exclusion zones to define areas where access is or is not allowed. Aircraft only. |
| Vector
|
Constrain access computations with respect to any valid vector or angle. |
| Special
|
Special access constraints are defined in terms of geostationary belt exclusion, height above horizon, terrain grazing angle and exclusion of other scenario objects. |
| Plugins
|
An interface is provided for defining custom constraints in terms of user-supplied scripts created in VBScript and MATLAB. |
RF Properties
| Property |
Description |
| Environment
|
Apply environmental factors that affect the performance of a communications link or a radar system.
|
LASER Properties
| Property |
Description |
| Environment
|
Apply environmental factors that affect the performance of a laser communications link. |
