Detailed Description

An RF attenuation model that can include the effects of dust, rain and clouds.

This model utilizes frequency-dependent lookup-tables and formulas to compute the attenuation of the atmosphere, dust, rain and clouds on RF signals in the 1 - 90 GHZ frequency range.

Note

This model was provided for a specific project application. It is assumed that the sensor is on an aircraft at a reasonable high altitude looking down at ground targets.

Member Function Documentation

Clone()

WsfEM_Attenuation * WsfEM_RF_Type1Attenuation::Clone ( ) const

overridevirtual

Return a copy of this object. Must be implemented by all derived types. If cloning is impossible, a WsfUncloneableException should be thrown.

Implements WsfEM_Attenuation.

References WsfEM_Attenuation::WsfEM_Attenuation(), and WsfEM_RF_Type1Attenuation().

ComputeAttenuationFactorP()

double WsfEM_RF_Type1Attenuation::ComputeAttenuationFactorP ( double aRange, double aElevation, double aAltitude, double aFrequency )

overrideprotectedvirtual

Compute the attenuation loss factor along a specified path.

Parameters

aRange	The range over which the signal will travel (meters)
aElevation	The elevation angle above the horizontal plane that is tangent to the Earth's surface (radians)
aAltitude	The altitude of the lowest point between the two points under consideration. This altitude must be lowest as some models assume it.
aFrequency	The frequency of the signal (hertz).

Returns

The fraction of the signal that remains at the end of the path, in the range [0, 1].

Note

This form is NOT called directly by the routines in WsfEM_Interaction (they call the 3-argument form). The base class 3-argument form calls this form, which as a signature that is typical for many RF models.

This form is protected and can ONLY be called by the base class 3-argument form.

Reimplemented from WsfEM_Attenuation.

Initialize()

bool WsfEM_RF_Type1Attenuation::Initialize ( WsfEM_XmtrRcvr * aXmtrRcvrPtr )

overridevirtual

Initialize the attenuation object.

Parameters

aXmtrRcvrPtr

The transmitter/receiver to which the attenuation object is attached.

Reimplemented from WsfEM_Attenuation.

References WsfEM_XmtrRcvr::GetPlatform(), and WsfPlatform::GetScenario().

ObjectFactory()

WsfEM_Attenuation * WsfEM_RF_Type1Attenuation::ObjectFactory ( const std::string & aTypeName )

static

Factory method for WsfEM_Attenuation. This is called by WsfEM_Attenuation::LoadInstance to determine if a model represented by this class is being requested.

WsfEM_RF_Type1Attenuation & WsfEM_RF_Type1Attenuation::operator= ( const WsfEM_RF_Type1Attenuation & )
