INSTALLATION RADAR DU TYPE A MODULATION DE FREQUENCE ET A ONDES ENTRETENUES, A L'ABRI DES SIGNAUX FANTOMES, AYANT POUR ROLE D'AVERTIR UN CONDUCTEUR QU'IL SERRE DE TROP PRES UN AUTRE VEHICULE

INSTALLATION RADAR A MODULATION DE FREQUENCE ET A ONDES ENTRETENUES POUR AUTOMOBILES.CETTE INSTALLATION EMET UN FAISCEAU D'ONDES RADIO DONT LA FREQUENCE D'OSCILLATION EST MODULEE A UNE VALEUR DONNEE. LA RECEPTION DES ONDES REFLECHIES PAR UN OBJET PERMET DE DETERMINER LA DISTANCE ENTRE LE VEHICULE ET CET OBJET AU MOYEN DES SIGNAUX DE FREQUENCE DE BATTEMENT. L'INSTALLATION COMPREND DES MOYENS SERVANT A DIVISER LES SIGNAUX DE FREQUENCE DE BATTEMENT EN UNE SERIE DE BANDES DE FREQUENCES SECONDAIRES EGALES ENTRE ELLES, ET A DETECTER CES SIGNAUX DE FREQUENCE DE BATTEMENT AINSI DIVISES, DES MOYENS DE TRAITEMENT DES SIGNAUX CONCUS POUR OPERER DE FACON ARITHMETIQUE D'UNE MANIERE PREDETERMINEE. An FM-CW type radar system, for use in an automotive vehicle, which is specifically designed with a signal processor of relatively simple construction having an improved capability of identifying an object, particularly a plurality of objects, to be identified in suurrounding traffic or road areas. The system is particularly effective in overcoming possible error in detection of the object(s) due to reflected or scattering waves from the road surface or the like as experienced in the general radar navigation system for detecting the approaching or interfering object(s) by the provision of incessant radar monitoring along with the path of travel of the vehicle equipped with the radar system so as to eventually maintain a safe relative distance and/or velocity of that vehicle with respect to the object(s) in the surrounding traffic or road areas.
