Indoor Operations by FMCW Millimeter Wave SAR Onboard Small UAS: A Simulation Approach

Figure 3

Schematic of 2D grid values. Areas associated with value 0 represent the propagating medium; cells having values ranging from 1 to 8 are the walls. Receiving antenna is represented by value 9. Size of grid cells with respect to total size of grid is not to scale, for clarity.
