MDV determines whether the majority of military traffic, which often moves very slowly, will be visible. To capture the majority of this traffic, a radar must have the ability to detect the lowest possible radial velocity. As a target's radial velocity approaches zero, the target will fall into the clutter or "blind zone. "The clutter spread is a function of a radar's antenna real bandwidth. When a target is in clutter, traditional MTI [moving target indicator] radars can either detect the target or locate it, but not both.  1, record 1, English, - minimum%20detectable%20velocity

In a coherent moving target indicator system using a uniform repetition rate, the blind speed is the radial velocity at which the moving target changes distance by one-half wavelength(or multiples thereof) during each pulse period.  2, record 2, English, - radar%20blind%20speed

Pour lutter contre [les vitesses aveugles], il y a deux moyens: - faire varier [la fréquence de récurrence] (wobbulation de la fréquence de récurrence), - émettre sur plusieurs longueurs d'ondes et choisir le meilleur échos et sommer les échos de sortie de la VCM (radar diversité); (...)  1, record 7, French, - wobbulation%20de%20la%20fr%C3%A9quence%20de%20r%C3%A9currence

On peut cependant remédier assez facilement à cette situation [vitesse aveugle] en faisant varier F de quelques pour-cent à chaque récurrence, c'est-à-dire en wobbulant la fréquence de répétition du radar.  3, record 7, French, - wobbulation%20de%20la%20fr%C3%A9quence%20de%20r%C3%A9currence
