Patent ID: 7639172

Claim:
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 (x i , y j , 0), where x i and y j 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 ƒ ij such that for each pair (x,y) of real numbers satisfying |x−x i |≦ε x and |y−y j |≦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)−ƒ ij ∥≦ε M where ε M is a given real threshold and ∥ ∥ is a norm suited to the type of the measurements.
