Detailed Description

Header for radar channel propagation and interaction models.

This file contains the declarations for functions that model the radar channel, including direct and reflected signal path calculations, and power scaling according to the radar range equation. These functions form the core physics engine for determining the properties of a received signal based on the positions and velocities of transmitters, receivers, and targets.
