Abstract
A method for imaging an area of interest on the ground uses a georadar equipped with a plurality of transmitter antennas and a plurality of receiver antennas. A bistatic RCS matrix is calculated at each point of a grid based on the matrix representing the MIMO channel modelling the propagation and the reflection in the area of interest, a matrix representing the losses along the propagation paths of the channel, and a phase-shifter matrix representing the delays on these same propagation paths. The bistatic RCS matrices relating to discrete frequencies belonging to the same coherence sub-band are summed and the elements of the matrices thus obtained are then summed incoherently to provide an overall backscatter coefficient for each point of the grid. Afterwards, an image representing this backscatter coefficient at each point of the grid is generated. A method for detecting a ground target-uses the same principle.
