    摘要: A process for modelling of ground clutter received by a radar, starting from a meshed numerical terrain model, including identifying cells from the meshed numerical terrain model which comprise elements having a height greater than a resolution of the model; determining, for relevant cells, an average height of the elements; sectioning the relevant cells into height-wise slices; and calculating power backscattered by each of the relevant cells by representing contents thereof with elementary reflectors distributed over an entire height thereof as a function of adjoining cells and a profile of terrain situated between the radar and a relevant cell.
