Additional Radar Constraints

Constraints with Jamming

The S/T w/Jamming , and SAR w/Jamming pages of a radar's Constraint properties allow you to take account of the effects of jamming in connection with all Search/Track Constraints as well as several SAR Constraints. Like their counterparts, these constraints can be used to compute an object's Access visibilities and also provide new Figures of Merit for Coverage and Attitude Coverage.

To isolate the effects of jamming, you can set a given constraint with jamming and its counterpart without jamming. Examples would be Single Pulse S/(N+J) and Single Pulse SNR (for Search/Track) or S/(N+J) and SNR (for SAR). If there is no jamming present (or if jamming is not being computed), of course, the results for each constraint in the pair will be identical.

Also, jamming-to-signal ratio constraints can be set for Search/Track (J/S and Integrated J/S) and SAR (SAR J/S) radars.
