METHOD FOR GUIDING AN AIR TARGET, IN PARTICULAR IN A VERTICAL LANDING PHASE, AND RADAR SYSTEM USING SUCH A METHOD

摘要

The method comprises at least: a first radar processing (21) for locating and estimating the trajectory of said target (1) from measurements of radial distances, Doppler frequency and azimuth angle and elevation said target (1) derived from a radar signal transmitted to said target (1); - a second radar processing (21) of location and trajectory of said target (1) along a vertical axis, by applying the principle of the reverse synthetic antenna; the difference between said given trajectory and the trajectory estimated by said first projected treatment on a horizontal plane and the difference between said given trajectory and the trajectory estimated by the second treatment along said vertical axis being used to control the direction of movement of said target (1).
