Abstract : Photonics technology offers many advantages when applied to phased array antenna problems. These advantages include small size, low weight, low loss, wide bandwidth, and advanced signal processing functions such as high-resolution, broadband, amplitude and phase control, variable true time delay, and broadband correlation for jammer nulling. This one-year study contract investigated the use of integrated optical circuits for high-resolution amplitude and phase control of super high frequency (SHF) signals. Airborne and space-based, transmit and receive phased array antennas were designed. The antenna designs are compatible with the Defense Satellite Communications System (DSCS) bands--7.25 to 7.75 GHz downlink and 7.9 to 8.4 GHz uplink.
