Use STK Radar to identify jammers and assess their impact on the performance of your radar system.
Use the Jamming tab on the Radar's Basic Definition page to enable jamming computations and add and remove jammers in your jamming analysis. Only qualified assets will appear in the Available Jammers list, from which you can assign transmitters as jammers. Any monostatic radar can function as a jammer. If your scenario contains bistatic radars or retransmitters, you will not see them here.
Also, you can set SAR or Search Track constraints for a jammer, and include the effects of jamming in Coverage and Attitude Coverage analyses.
Compute jamming
Select or clear the Use check box to enable or disable the computation of jamming effects. Use this to turn off jamming analysis temporarily without having to dismantle your jamming setup; i.e., it is not necessary to remove jammers, turn off constraints, etc. Disabling jamming computation will save you processing time if you want to make and test other changes in the scenario without having to recompute jamming each time. This can be especially helpful in a scenario that includes many jammers.
You must enable jamming computations to have the effect of the assigned jammers taken into account.
Assigning jammers
To add an asset as a jammer from the Available Jammers list, double-click it or select it and click the right arrow button to copy it to the Assigned Jammers area. To remove it from the Assigned Jammers area, double-click it or select it and click the left arrow button .
Use the Selection filter to assign two or more objects by class. To select all objects of a given class (Radar or Transmitter), select the check box for that class. You can then assign all the objects of that class as jammers by clicking the right arrow button. You can then remove individually selected objects using the procedure described above.
You can also use multiselect techniques to manage large lists of Available and Assigned Objects.
Radar jamming objects (jammers) can occupy the Radar's parent object in the STK object browser, but jamming computations will only occur if the jammer and Radar are physically separated by an offset distance.
A tutorial on jamming analysis accompanies this Help system.
SAR or Search Track constraints
If you need a constraint on your radar system for system parameters infracted by jamming, then set Search/Track constraints and SAR constraints that take jamming into account.
Effects of jamming on Coverage and Attitude Coverage
You can include the effects of jamming in Coverage and Attitude Coverage analyses. You can select a radar object as the associated class in defining the basic grid for the Coverage Definition or Attitude Coverage. If you then select Access Constraint as the Figure of Merit Definition, the available constraints for the radar, including those that take jamming into account, appear in the Constraints list.
