Detailed Description

Plane wave arrival Delays for Radio Imaging.

RdWaveModel is to calculate geometrical time delay of signal arrival relative to an origin, based on a spherical wave front model.

The delay is for a plane wave front

\[ \tau_{j} = \frac1{c} \frac{\left<\vec\rho,\vec x_j\right>} {|\vec\rho|} \]

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