Report Style: Radar SAR

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. The data includes the time-resolution product, max scene width, integration time, azimuth and range resolutions, area rate, noise density, SNR, SCR, CNR, and PTCR.

Data Provider:Radar SAR

Type: Time-varying data.

Availability: Reports | Dynamic Displays

Column Listing

Column	Column Name	Element	Type	Dimension	Description
1	Access	Access Number	Integer	Unitless	The number of the current access interval from the list of access intervals.
2	Time	Time	Real Number or Text	Date	Time.
3	SAR Time-Resolution Prod	SAR Time-Resolution Prod	Real Number	SARTimeResProd	Computed as lambda/(2 * xyAngleRate)
4	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
5	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
6	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
7	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
8	SAR Area Rate	SAR Area Rate	Real Number	Area Rate	Computed as (sceneDepth * maxdSceneWidth)/(cos(Grazing) * integrationTime)
9	Noise Density	Noise Density	Real Number	PowerSpectralDensity	The composite value of the carrier to noise density ratio (C/No) across all hops of an analog bent pipe communications link where C is the carrier power and No = kT (Boltzmann's constant x system temperature) is the noise density. Note that C/No is equivalent to C/N with a normalized Bandwidth (B=1).
10	SAR SNR	SAR SNR	Real Number	Ratio	Signal power to Noise power ratio for a SAR
11	SAR SCR	SAR SCR	Real Number	Ratio	Signal power to Clutter power ratio for a SAR
12	SAR CNR	SAR CNR	Real Number	Ratio	Clutter power to the Noise power ratio for a SAR signal
13	SAR PTCR	SAR PTCR	Real Number	Ratio	Point Target Clutter Ratio for a SAR
14	SAR Add Noise Coef	SAR Add Noise Coef	Real Number	Ratio	Ratio of the clutter coefficient to the clutter-to-noise ratio (CNR)
15	SAR Noise Bandwidth	SAR Noise Bandwidth	Real Number	Bandwidth	Radar receiver's RF front-end LNA bandwidth
16	SAR Noise Power	SAR Noise Power	Real Number	Power	Total noise power, as seen by the radar receiver across its RF bandwidth
