Radar Constraints

There are several categories of constraints applicable specifically to radar systems: Search/Track, Multifunction Radar Search/Track, SAR, and Bistatic constraints.

The Search/Track, Multifunction Radar Search/Track, and SAR constraint categories can also be set for facilities, targets, and vehicles - though the settings will only have an effect on the scenario if one of the access objects is a radar.

Search/Track Constraints

You can enter minimum and maximum values for the following types of Search/Track constraints:

  • 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.
  • Multifunction Radar 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.
  • Multifunction Radar S/T 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.
  • 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.
  • 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 RadarSearch/Track computation and constraints can be extended with the Search/Track plugin constraint. See Custom Plugins for Radar Search/Track and SAR Constraints.

SAR Constraints

You can impose a variety of constraints on SAR (synthetic aperture 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 and SAR plugin constraint. See Custom Plugins for Radar Search/Track and SAR Constraints.

Bistatic Constraints

If your radar is set up as bistatic, you can set Bistatic constraints.
