Dynamic range of quadrature radio-frequency time-integrating acoustooptic correlator

A new time-integrating acoustooptic correlator (TIAOC) was developed. It combines relatively low complexity with an exceedingly wide band of analyzed signals. The main feature of the architecture is the use of light beam interference to provide the quadrature processing channel. The dynamic range (D...

Zusammenfassung:A new time-integrating acoustooptic correlator (TIAOC) was developed. It combines relatively low complexity with an exceedingly wide band of analyzed signals. The main feature of the architecture is the use of light beam interference to provide the quadrature processing channel. The dynamic range (DR) of the new TIAOC is calculated for the active and passive operating modes. Parameter optimization to achieve the maximum DR is performed. The photodetector charge handling capacity is shown to be the main DR limiter
