The Target Object
The Target object models a point of interest on the surface of the central body. Select one or more of the following to model a target, impose constraints, and define the target's subobjects:
- Basic properties
- 2D Graphics properties
- 3D Graphics properties
- Constraints
- RF properties
- Laser Properties
- Subobjects
Basic Properties
Property | Description |
---|---|
Position | Define the location of the target using one of several available position types. |
AzElMask | Use terrain data or a mask file to define an azimuth-elevation mask for the target. |
Terrain Slope | Define the scope of the local terrain. |
Description | Record useful information about the target. |
2D Graphics Properties
Property | Description |
---|---|
Attributes | Define color and marker style for the target, and opt whether to inherit or override the global setting for label display. |
AzElMask | Control the display of azimuth-elevation mask properties in the 2D Graphics window. |
Range | Define range contours representing the various regions of the surface that can see an object at the specified level. |
Display Times | Set time intervals during which target graphics display. |
Radar Cross Section | Define the 2D contour graphics for the desired frequency. |
3D Graphics Properties
Property | Description |
---|---|
Vector | Control the display of vectors and other geometric elements related to the target. |
Attitude Sphere | The Attitude Sphere is a visualization aid that when combined with vector display constitutes a powerful tool for displaying the object's attitude and for tracking attitude changes over time. |
Model | Specify a model to represent a particular target in the 3D Graphics window, and then scale the model and adjust the position of any model articulations. |
Offsets | Position a model and marker representing a target in the 3D Graphics window by offsetting the object from its reference frame. |
AzElMask | Control the display of azimuth-elevation mask properties in the 3D Graphics window. |
Range | Display range contours for a specific STK target. Range contours display in accordance with the values set for 2D Graphics Range Contours for the object. |
Model Pointing | Point parts of a target model toward a target, such as the Sun or Earth. |
Data Display | Display dynamic data for the specified target in the 3D Graphics window. |
Vapor Trail |
Add a vapor trail to the target. |
Radar Cross Section | Control the 3D display of RCS contour lines. |
Constraints
Property | Description |
---|---|
Basic | Impose a variety of standard access constraints (azimuth and elevation angle and rate, range and range rate, propagation delay, etc.) from the target to another object. |
Sun | Impose a variety of access constraints from the target to another object based on the position of the Sun and the Moon. |
Temporal | Impose time-based access constraints from the target to another object. |
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. |
Search/Track |
Radar Search/Track Constraints property pages enable you to enter minimum and maximum values for several parameters. You can also choose from the following Doppler options:
You can extend the STK Radar SAR computation and constraints with the Search/Track plugin constraint. See Search/Track User Plugin. |
SAR |
SAR property pages enable you to impose a variety of constraints on synthetic aperture (SAR) radar.
You can extend the STK Radar SAR computation and constraints with the Search/Track plugin constraint. See SAR User Plugin. |
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. |
Radar Cross Section | Specify the radar cross section (RCS) parameters. |
LASER Properties
Property | Description |
---|---|
Environment | Apply environmental factors that affect the performance of a laser communications link. |
