The Radar Object

The Radar object models the characteristics of a radar system and its environment. Select one or more of the following to model a Radar and impose constraints:

Basic Properties

Property Description
Definition Define the characteristics of the radar.
Refraction Model atmospheric refraction.
Description Record useful information about the antenna.

2D Graphics Properties

Property Description
Contours Define the display of contour lines and radar patterns.
Boresight Define the display of boresight graphics.

3D Graphics Properties

Property Description
Attributes Control the display of contour lines and radar patterns.
Vector Control the display of vectors and other geometric elements related to the radar.

Constraints

Property Description
Search/Track

Radar Search/Track Constraints property pages allow minimum and maximum values to be entered for several parameters and presents a variety of doppler options:

  • Search/Track. These parameters correspond to the radar's main channel. These parameters account for the polarization mismatch, if polarization is selected on the Basic Polarization page.
  • ST w/Jamming. These parameters correspond to the main channel radar receiver that is under the influence of jamming. When the radar receiver polarization is set and the jammers are polarized, the search/track parameters take polarization mismatch into account. Most of these parameters are re-computed under the impact of jamming on the radar receiver main channel. For more information on the effects of jamming on constraints, see Constraints with Jamming.
  • S/T OrthoPol. These parameters correspond to the radar's orthogonal polarization channel.
  • S/T OrthoPolJam. These parameters correspond to the radar's orthogonal polarization channel under the threat of jamming.

The STK/Radar SAR computation and constraints can be extended with the Search/Track plug-in constraint. See Search Track User Plugin.
SAR

SAR property pages allow for the imposition of a variety of constraints on synthetic aperture (SAR) radar.

  • SAR. These parameters correspond to the main channel (SAR).
  • SAR w/Jamming. These parameters correspond to the main channel under jamming. For more information on the effects of jamming on constraints, see Constraints with Jamming.
  • SAR OrthoPol. These parameters are enabled when the receiver side orthogonal polarization is selected.
  • SAR OrthoPolJam. These parameters are enabled when the receiver side orthogonal polarization is selected. For more information on the effects of jamming on constraints, see Constraints with Jamming.

The STK/Radar SAR computation and constraints can be extended with the Search/Track plug-in constraint. See SAR User Plugin.
Bistatic Enforce access constraints between the transmitter and receiver and set minimum and maximum values for the bistatic angle. While other access constraints are always enforced between the bistatic transmitter and the target/receiver, radar-specific constraints defined for a bistatic transmitter do not constrain access for the radar using it.
Basic Impose minimum elevation and line-of-sight constraints on access from the radar to another object.
Noise Impose constraints on a radar related to system noise temperature.
Sun Impose a variety of access constraints from the radar to another object based on the position of the Sun and the Moon.
Temporal Impose time-based access constraints from the radar to another object.
Advanced impose a variety of radar-specific constraints.
Zones Use inclusion and exclusion zones to define areas where access is or is not allowed.
Targeting Define the relationship between the radar and the target of that radar.
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 Perl, VBScript and MATLAB.
