Abstract
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.
