1. A method for storing measurements of a given type made by a radar, each measurement M(x,y,z) having been made at a position (x,y,z) in a given coordinate system, where x, y and z are real numbers, the method comprising:

  • a step of accessing a structured data storage space (Π

    ), each location of which is addressable by a pair of positive integers and each location of which is able to store at least one evolution profile of the measurements of the given type as a function of the altitude z;

    a meshing step which associates a position (xi,yj,0), where xi and yj are real numbers, with a pair of positive integers (i,j) allowing a location to be addressed;

    a step of modifying the content of the location with the pair (i,j) as its address by storing there an evolution profile fij such that for each pair (x,y) of real numbers satisfying |x−

    xi|≦

    ε

    x and |y−

    yj|≦

    ε

    y, where ε

    x and ε

    y are given real thresholds, for which a measurement M(x,y,z) has been made at an altitude z, ∥

    M(x,y,z)−

    fij



    ε

    M where ε

    M is a given real threshold and ∥



    is a norm suited to the type of the measurements.
