Wave Front

ArcComponent

__init__(idx, Pw, Gt_lin)

Arc component unit for a WaveFront simulation. The ArcComponent its the tinnest non redundant area of the simulation to detect a target.

Parameters:

Name	Type	Description	Default
Idx	int	Index of ArcComponent of the wavefront simulation instance	required
Gt	float	Gain of the transmitting antenna (in \(dBi\)).	required
R	float	Range to the target in meters (\(m\)).	required

compute_power_db(R)

Arc component unit for a WaveFront simulation. To calculate the power at a distance (\(R\)) by a radar system, we can use the radar range equation, which is given by:

\[ \begin{equation} P_w = \frac{P_t \cdot G_t}{(4\pi)R^2} \end{equation} \]

Where

• \(P_w\) is the power received by the radar in watts (\(W\)).
• \(P_t\) is the transmitted power in watts (\(W\)).
• \(G_t\) is the gain of the transmitting antenna.
• \(R\) is the range to the target in meters (\(m\)).

Parameters:

Name	Type	Description	Default
R	float	Range to the target in meters (\(m\)).	required

Returns:

Name	Type	Description
Pr_dBW	float	Power received by the radar in decibels with respect to one watt (\(dBW\)).
