Detailed Description

A concrete class that provides a minimal implementation of SOSM_Interaction.

This class provides a minimal implementation of SOSM_Interaction for those uses where the simulation may not be maintaining this data by itself. Methods are provides to either set the values directly or by calling one of the ComputeGeometry methods to compute the required data based on the supplied parameters.

GetAbsoluteTargetElevation()

float SOSM_SimpleInteraction::GetAbsoluteTargetElevation ( )

inlineoverridevirtual

Return the elevation of the target with respect to the horizontal plane at the sensor location.

This method should returns the elevation angle of the target location with respect to a plane that is tangent to the Earth's surface at the sensor location. It is NOT a function of the orientation of either the sensor or the target.

Returns

elevation angle in radians (+ up, - down)

Implements SOSM_Interaction.

GetSensorAltitude()

float SOSM_SimpleInteraction::GetSensorAltitude ( )

inlineoverridevirtual

Return the altitude of the sensor.

Returns

The altitude of the sensor (meters/second).

Implements SOSM_Interaction.

GetSensorSpeed()

virtual float SOSM_SimpleInteraction::GetSensorSpeed ( )

inlinevirtual

GetSensorToTargetAspect()

void SOSM_SimpleInteraction::GetSensorToTargetAspect ( float & aAzimuth, float & aElevation )

inlineoverridevirtual

Return the aspect of the target with respect to the sensor.

This method should return the azimuth and elevation of the target platform with respect to the location AND orientation of the sensor platform (NOT the installed sensor angle).

Parameters

aAzimuth	[output] The azimuth angle (radians). Positive values are to the RIGHT with respect to the 'pilot' on the sensor platform.
aElevation	[output] The elevation angle (radians). Positive values are UP with respect to the 'pilot' on the sensor platform.

Implements SOSM_Interaction.

GetSlantRange()

float SOSM_SimpleInteraction::GetSlantRange ( )

inlineoverridevirtual

Return the slant range between the sensor and the target. The slant range between the sensor and the target (meters)

Implements SOSM_Interaction.

GetTargetAltitude()

float SOSM_SimpleInteraction::GetTargetAltitude ( )

inlineoverridevirtual

Return the altitude of the target.

Returns

The altitude of the target (meters).

Implements SOSM_Interaction.

GetTargetSpeed()

float SOSM_SimpleInteraction::GetTargetSpeed ( )

inlineoverridevirtual

Return the speed of the target.

Returns

The speed of the target (meters/second).

Implements SOSM_Interaction.

GetTargetThrottle()

float SOSM_SimpleInteraction::GetTargetThrottle ( )

inlineoverridevirtual

Return the 'throttle setting' of the target.

Returns

The throttle setting of the target in the range [0..1].

Note

The following values should be used as indicated:

• 0.0 = no power applied.
• 1.0 = afterburner activated.

Reimplemented from SOSM_Interaction.

GetTargetToSensorAspect()

void SOSM_SimpleInteraction::GetTargetToSensorAspect ( float & aAzimuth, float & aElevation )

inlineoverridevirtual

Return the aspect of the sensor with respect to the target.

This method should return the azimuth and elevation of the sensor platform with respect to the location AND orientation of the target. This is used for target signature determination.

Parameters

aAzimuth	[output] The azimuth angle (radians). Positive values are to the RIGHT with respect to the 'pilot' on the target platform.
aElevation	[output] The elevation angle (radians). Positive values are UP with respect to the 'pilot' on the target platform.

Implements SOSM_Interaction.
