AeronauticalStatisticalModel()

PROPLIB_API ReturnCode ITS::ITU::PSeries::P2108::AeronauticalStatisticalModel	(	const double	f__ghz,
		const double	theta__deg,
		const double	p,
		double &	L_ces__db )

The Earth-space and aeronautical statistical clutter loss model as described in Section 3.3.

This model is applicable when one end of the path is within man-made clutter and the other end is a satellite, aeroplane, or other platform above the Earth.

Frequency range: \( 10 < f < 100 \) (GHz)
Elevation angle range: \( 0 < \theta < 90 \) (degrees)
Percentage locations range: \( 0 < p < 100 \) (%)

Parameters

[in]	f__ghz	Frequency, in GHz
[in]	theta__deg	Elevation angle, in degrees
[in]	p	Percentage of locations, in %
[out]	L_ces__db	Additional loss (clutter loss), in dB

Returns

Return code

cot()

double ITS::ITU::PSeries::P2108::cot

(

const double

x

)

Helper function to calculate \( \cot(x) \).

The calculation is implemented simply as \( 1 / \cot(x) \).

Parameters

[in]

x

Argument, in radians

Returns

Cotangent of the argument, \( \cot(x) \)

Section3p3_InputValidation()

ReturnCode ITS::ITU::PSeries::P2108::Section3p3_InputValidation	(	const double	f__ghz,
		const double	theta__deg,
		const double	p )

Inputs-in-range validation for the Earth-space and aeronautical statistical clutter loss model (Section 3.3).

Returns SUCCESS if all parameters are valid. Otherwise, invalid inputs will return unique error codes.

Frequency range: \( 10 < f < 100 \) (GHz)
Elevation angle range: \( 0 < \theta < 90 \) (degrees)
Percentage locations range: \( 0 < p < 100 \) (%)

Parameters

[in]	f__ghz	Frequency, in GHz
[in]	theta__deg	Elevation angle, in degrees
[in]	p	Percentage of locations, in %

Returns
