Abstract

In-phase (I) and quadrature (Q) signal processing is required when signal phase information is needed, such as to prevent effects like blind phase in pulsed moving target indicator (MTI) radar. A photonic I-Q processor is proposed and experimentally demonstrated for low frequency (e.g., sub-Hz - 15 MHz), radio frequency (e.g., 107 - 133 MHz) and microwave frequency band (e.g., 800 - 1000 MHz) signal processing. Applications for our I-Q processor include signal processing for sonar, ultrasound, radar, and communication radar receivers.
