Procedure and device for signal processing based on a transmission mixer, frequency multiplication and subharmonic mixing

摘要

Process for signal processing, in which an input signal (fLO), which exists in a first component, is conducted by this first component (101) to a second component (201), which can operate as a frequency multiplier and as a subharmonic mixer; - in which the second component (201) by means of at least one piece with a non-linear characteristic curve (203) multiplies the frequency of the obtained signal (3fLO); - in which the first component (101) is a transmission mixer, which retransmits the input signal to the second component and in the opposite direction, in which the signals are provided by the second component, has a downward mixing functionality, - wherein the signal multiplied by frequency (3fLO) provided by the second component (201), is emitted through an antenna (301), - in which by means of the antenna (301) a signal is received (3fLO + fdoppler) and the received signal is mixed subharmonically (fLO + fdoppler) by the second component (201) and retransmitted to the first component (101), - in which the signal retransmitted by the second component to the first component is mixed down by the first component, in which the first component provides, after mixing downwards, a signal with the frequency where f1 designates the frequency (fLO) of the input signal and / or the frequency (fLO) of the signal provided to the second component. or the first component and f3 the frequency of the signal, mixed subharmonically by the second component and retransmitted to the first component,
