Abstract
L'invention concerne la détermination de la distance minimale d'approche entre deux objets en mouvement relatif. Pour déterminer la distance minimale d'approche entre une cible T et un missile W qui est tiré vers cette cible, la cible porte un radar Doppler qui mesure en permanence la vitesse radiale du missile, et qui retransmet au sol, par télémesure, les données, correspondantes. Cette vitesse radiale s'annule au point d'approche minimale P, et la forme de la courbe de variation de la vitesse radiale permet de calculer au sol la distance d'approche minimale M. Applications aux essais de missiles.
