Abstract

Ce radar de puissance (20) comporte au moins une antenne émettrice (1), émettant des signaux impulsionnels dans une bande de fréquences donnée à partir d'un générateur d'impulsions (4a) et d'un générateur de signaux porteurs (4b), ces générateurs (4a, 4b) étant couplés via un mélangeur (5e) à un module d'amplification de puissance (M1) comprenant au moins un amplificateur de puissance (2), une antenne de réception (3a) de signaux dans la même bande de fréquences donnée, et un module de traitement de signal (M2) en liaison avec l'antenne de réception (3a). Le module d'amplification de puissance (M1) étant connecté à un réseau d'alimentation électrique (9) de tension continue. le module d'amplification de puissance (M1) contient un matériau à base de nitrure de gallium (GaN) et la tension du réseau électrique (9) auquel il est connecté est sensiblement supérieure à 12 V, ce réseau électrique (9) étant apte à alimenter une motorisation hybride d'entraînement des véhicules automobiles.This power radar (20) comprises at least one transmitting antenna (1), emitting pulse signals in a given frequency band from a pulse generator (4a) and a carrier signal generator (4b) , these generators (4a, 4b) being coupled via a mixer (5e) to a power amplification module (M1) comprising at least one power amplifier (2), a signal receiving antenna (3a) in the same given frequency band, and a signal processing module (M2) in connection with the receiving antenna (3a). The power amplification module (M1) is connected to a DC voltage supply network (9). the power amplification module (M1) contains a material based on gallium nitride (GaN) and the voltage of the electrical network (9) to which it is connected is substantially greater than 12 V, this electrical network (9) being suitable to power a hybrid motor drive motor vehicle.
