Detailed Description

Spherical wave arrival Delays for Radio Imaging.

RdWaveModel is to calculate geometrical time delay of signal arrival relative to an origin. By default, calculation is based on a spherical wave front model. A plane wave model is providid by the subclass RdPlaneDelays.

The delay is for a spherical wave front

$\tau_{j} = \frac1{c} \left( |\vec x_j - \vec\rho| - |\vec\rho| \right)$

Delay calculation code is inspired by the LOPES code by Lars B"ahren
