Set the antenna properties of a radar (Deprecated Command)
Radar <RdrObjectPath> Antenna {AntennaType} <Parameters>
Note: This command was deprecated in STK 10.1, it should no longer be used. This command has been replaced by the Radar command.
The Radar Connect commands were enhanced in STK 10.1 to make use of attributes and to simplify the format required to use these commands. For more information on using the new format see Transitioning to the New Radar Format.
The Radar module features several analytical antenna models for your use. The Radar Antenna command allows you to set the model and associated parameters needed to use any of these models.
Available options for {AntennaType} and associated <Parameters> are:
| {AntennaType} | <Parameters> | Description |
|---|---|---|
| Gaussian | <Efficiency> <Value1> [{ComputeOption}] |
<Efficiency> is between 0.001 and 1.0 {ComputeOption} can be Size, BeamWidth or MaxGain If {ComputeOption} is Size, then <Value1> is the dimension entered in small distance units, between 0.001 and 1000 meters If {ComputeOption} is BeamWidth, then <Value1> is the beamwidth entered in degrees, between 0.001 and 90 deg If {ComputeOption} is MaxGain, then <Value1> is the gain entered in dB, between 0.0 and 1000 |

<SideLobeGain> is entered in dB, between -500.0 and -3.0 {ComputeOption} can be MainLobeGain, Azimuth or Elevation If {ComputeOption} is MainLobeGain,then <Value1> and <Value2> are azimuth and elevationIf {ComputeOption} is Azimuth, then <Value1> and <Value2> are elevation and main lobe gain If {ComputeOption} is Elevation, then <Value1> and <Value2> are azimuth and main lobe gain Azimuth and Elevation values are entered in degrees, between 0.001 and 90.0. Main lobe gain value is entered in dB, between -500.0 and 1000.0. |

<MainLobeGain> is entered in dB greater than 0.0 <SideLobeGain> is entered in dB less than 0.0 <MaxAngle> is entered in degrees between 0.0 and 180.0 {GainEffects} can be On or Off Warning: <MaxAngle> and {GainEffects} should only be specified if you're running STK Radar version 1.0. These parameters should not be used for later versions of Radar. |
| External | "<FilePath>" | "<FilePath>", is the full path and file name for the antenna pattern file. |
| Dipole | <Efficiency> <Length> |
<Efficiency> is between 0.0 and 1.0 <Length> is entered in Connect distance units, between 0.001 and 1000000.0 meters. |
| CosecantSquared | <Alpha1> <Alpha2> {<AzimuthBeamwidth> <AlphaMAngle> | <AzimuthStart> <AzimuthStop> <Elevation>} <MainLobeGain> <SideLobeGain> <Efficiency> |
<Alpha1> is entered in degrees, between 0.0 and 90.0 <Alpha2> is entered in degrees, between 0.0 and 90.0 <AzimuthBeamwidth> is entered in degrees, between 0.0 and 60.0 <AlphaMAngle> is entered in degrees, between 0.0 and 90.0 <AzimuthStart> is entered in degrees, between 0.0 and 360.0 <AzimuthStop> is entered in degrees, between 0.0 and 360.0 <Elevation> is entered in degrees, between 0.0 and 90.0 <MainLobeGain> is entered in dB, between -500.0 and 1000.0 <SideLobeGain> is entered in dB, between -500.0 and 0.0 <Efficiency> is between 0.0 and 1.0 |
| Aperture | {ApertureType} <ApertureParameters> | See table below for Aperture description |
If {AntennaType} is Aperture, {ApertureType} and associated <ApertureParameters> can be:
| {ApertureType} | <ApertureParameters> |
|---|---|
| Cosine | {Dimension | BeamWidth} <XValue> <YValue> <MainLobeGain> <Efficiency> [<BackLobeGain>] |
| CosSquare | {Dimension | BeamWidth} <XValue> <YValue> <MainLobeGain> <Efficiency> [<BackLobeGain>] |
| CosPedestal | {Dimension | BeamWidth} <XValue> <YValue> <MainLobeGain> <EdgePedestal> <Efficiency> [<BackLobeGain>] |
| CosSqrPedestal | {Dimension | BeamWidth} <XValue> <YValue> <MainLobeGain> <EdgePedestal> <Efficiency> [<BackLobeGain>] |

| SincPowerX | {Dimension | BeamWidth} <XValue> <YValue> <MainLobeGain> <Power> <Efficiency> [<BackLobeGain>] |
| UniformRectangular | {Dimension | BeamWidth} <XValue> <YValue> <MainLobeGain> <Efficiency> [<BackLobeGain>] |
| UniformCircular | {Dimension | BeamWidth} <XValue> <MainLobeGain> <EdgePedestal> <Power> <Efficiency> [<BackLobeGain>] |
| CircularBesselEnvelope | {Dimension | BeamWidth} <XValue> <MainLobeGain> <EdgePedestal> <Power> <Efficiency> [<BackLobeGain>] |
If Dimension is entered then <XValue> and <YValue> are entered in Connect distance units, and should be between 0.01 and 1000.0 meters.
If BeamWidth is entered then <XValue> and <YValue> are entered in degrees. <XValue> should be between 0.001 and 90.0. <YValue> should be between 0.0 and 90.0.
Note: To define a Circular Aperture set <YValue> to 0.0
<MainLobeGain> is entered in dB, between 0.0 and 1000.0
<EdgePedestal> is entered in dB, between -300.0 and 0.0
<Efficiency> should be between 0.0 and 1.0
<Power> for SincPowerN and SincPowerX should be between 1.0 and 10.0
<Power> for UniformCircular and CircularBesselEnvelope should be between 0.0 and 3.0.
For SincPowerN, UniformCircular and CircularBesselEnvelope apertures the <Power> value entered will be rounded down to the nearest integer.
The user can optionally enter a <BackLobeGain> value. This value is entered in dB and should be between -1000.0 and 1000.0. If not entered then the default -30 dB is used.
To set a square horn antenna type for the TestRadar with an efficiency of 0.4 and a dimension of 1.3 m:

If activated, Connect returns an acknowledgement message.
