摘要： A millimeter wave radar target simulation system and method. The system includes a down-converter that converts a millimeter wave radar signal to an intermediate frequency, an electrical-to-optical modulator that modulates an optical signal based on the down-converted signal, an optical-to-electrical demodulator that demodulates an optical signal to an electrical signal, an optical delay line serving to delay a signal passing from the electrical-to-optical modulator to the optical-to-electrical demodulator, and an up-converter that converts the electrical signal from the optical-to-electrical demodulator to a frequency that simulates a millimeter wave target return. The method includes receiving a millimeter wave radar signal, down-converting the radar signal to an intermediate frequency, modulating the down-converted signal to an optical signal, delaying the optical signal, demodulating the delayed optical signal, and up-converting the demodulated signal to a signal having a frequency that simulates a millimeter wave radar target return.

摘要： A switch for selectively providing an input signal to an output terminal. The switch includes a first waveguide terminal, a second waveguide terminal, a reduced-width waveguide connecting the first waveguide terminal to the second waveguide terminal, and at least one switching element spanning the reduced-width waveguide between the first and second waveguide terminals. The reduced-width waveguide is configured to pass a signal from the first waveguide terminal to the second waveguide terminal when the at least one switching element is in a first state and block a signal when the at least one switching element is in a second state. In some embodiments, the switch also includes at least one additional waveguide terminal and the reduced-width waveguide also connects the first waveguide terminal to the at least one additional waveguide terminal.
