METHOD FOR GUIDING AN AERIAL TARGET, ESPECIALLY IN THE VERTICAL LANDING PHASE, AND RADAR SYSTEM IMPLEMENTING SUCH A PROCESS

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 of said target (1) originating 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 application of the principle of the reverse synthetic antenna; the difference between said given trajectory and the trajectory estimated by said first processing projected onto a horizontal plane and the difference between said given trajectory and the trajectory estimated by the second processing along said vertical axis being used to control the direction of movement of said target (1).
