Define (Sensor)
Define the basic properties of a sensor
Syntax
Define <SensorObjectPath> {Type} <TypeData>
Description
The Define command enables you to define a specified sensor instance. <TypeData> is dependent upon the {Type} of sensor specified.
Use the Point commands to further define and manipulate a sensor.
{Type} and <TypeData> can be:
| {Type} | {TypeData} |
|---|---|
| Conical | <InnerConeHalfAngle> <OuterConeHalfAngle> <MinClockAngle> <MaxClockAngle> [AngularRes <Value>] |
| HalfPower | <Frequency> <Diameter> [AngularRes <Value>] |
| Custom | "<FilePath>"
"<FilePath>" can be the path to a file on your local drive or the path to a file on an SDF server. See Specifying Paths for "<SDFFilePath>" syntax information. |
| Rectangular | <VerticalHalfAngle> <HorizontalHalfAngle> [AngularRes <Value>] |
| SAR | <MinElevationAngle> <MaxElevationAngle> <ForwardExclusionAngle> <AftExclusionAngle> {<ParentAltitude> | TrackParentAltitude {On | Off} } [AngularRes <Value>] |
| SimpleCone | <ConeAngle> [AngularRes <Value>] |
| EOIR | <AcrossScanSmearRate> [<Value>] The value is a double.
<AlongScanSmearRate> [<Value>] The value is a double. <JitterDataFile> [<file path>] <JitterDataFileFrequencySampling> [<Value>] The value is a double. <JitterDataFileSpatialSampling> [<Value>] The value is a double. <JitterType> Choose from the following string options: "LOS Gaussian", "Power Spectrum File", "MTF File", or "PSF/Realization File". <ProcessingLevel> Choose from the following string options: "Sensor Off", "Geometric Input", "Radiometric Input", or "Sensor Output". <ScanMode> Choose from the following string options: "2D Framing Array". <UseMotionBlur> [<Value>] The value is a BOOLEAN: yes, no, on, off, true, or false. The following options must appear in the command after any of the options above. <AddBand> ["Band Name"] [Band Options] Band options are listed in the next table. <ModifyBand> ["Band Name"] [Band Options] Band options are listed in the next table. <RemoveBand> ["Band Name"] If you use the Define command with Type=EOIR for a sensor that is already Type=EOIR, you will get a NACK response. |
Include the optional AngularRes <Value> parameter to set the angular separation between neighboring pattern points. <Value> is entered in degrees and can be 0.000001 to 90.0.
All Angle values are entered in degrees.
For EOIR sensors, when you choose the option <AddBand> or <ModifyBand>, you can then choose from the following Band Options:
| Band Option | Requirements Description |
