Report Style: Radar SAR with Jamming

This Access report provides the dynamic (spot) SAR mode radar performance data between the radar system and the selected spot point, which might be an STK object such as a facility, under the presence of the jamming signals. Data includes S/(N+J), S/(C+N+J), C(N+J), J/S, and jamming power.

Data Provider:Radar SAR

Type: Time-varying data.

Availability: Reports | Dynamic Displays

Column Listing

Column	Column Name	Element	Type	Dimension	Description
1	Time	Time	Real Number or Text	Date	Time.
2	SAR Time-Resolution Prod	SAR Time-Resolution Prod	Real Number	SARTimeResProd	Computed as lambda/(2 * xyAngleRate)
3	SAR Max Scene Width	SAR Max Scene Width	Real Number	Distance	Ratio of the quantity (pulse repetition frequency * azimuth resolution time) to the azimuth broadening factor
4	SAR Integration Time	SAR Integration Time	Real Number	Time	The integration time for the dwell of pulses; computed as (SAR Time Resolution / Az Resolution); you can also enter this value yourself
5	SAR Az Resolution	SAR Az Resolution	Real Number	Distance	Computed as (lambda * dopplerRes)/(2 * xyAngleRate*range); you may also enter the value based on radar system specs
6	SAR Rng Resolution	SAR Rng Resolution	Real Number	Distance	Computed as (c * Pulse Width)/(2 * Pulse Compression Ratio); you may also enter this value based on radar system specs
7	SAR Area Rate	SAR Area Rate	Real Number	Area Rate	Computed as (sceneDepth * maxdSceneWidth)/(cos(Grazing) * integrationTime)
