Title (EN) RECONFIGURABLE RADAR TRANSMITTER
(FR) ÉMETTEUR RADAR RECONFIGURABLE
Abstract:
(EN) Techniques that facilitate reconfigurable transmission of a radar frequency signal are provided. In one example, a system includes a signal generator and a power modulator. The signal generator provides a radar waveform signal from a set of radar waveform signals. The power modulator divides a local oscillator signal associated with a first frequency and a first amplitude into a first local oscillator signal and a second local oscillator signal. The power modulator also generates a radio frequency signal associated with a second frequency and a second amplitude based on the radar waveform signal, the first local oscillator signal and the second local oscillator signal.
(FR) La présente invention concerne des techniques qui permettent l’émission reconfigurable d’un signal de fréquence radar. Dans un exemple, un système comprend un générateur de signal et un modulateur de puissance. Le générateur de signal produit un signal de forme d’onde radar à partir d’un ensemble de signaux de forme d’onde radar. Le modulateur de puissance divise un signal d’oscillateur local associé à une première fréquence et une première amplitude en un premier signal d’oscillateur local et un deuxième signal d’oscillateur local. Le modulateur de puissance génère en outre un signal de radiofréquence associé à une deuxième fréquence et une deuxième amplitude sur la base du signal de forme d’onde radar, du premier signal d’oscillateur local et du deuxième signal d’oscillateur local.
