• Data Collection Using Adaptive Phased Array

      Noji, T. T.; AIL (International Foundation for Telemetering, 1975-10)
      Adaptive Ground Implemented Phased Array or AGIPA provides a rapid and cost effective means to read out and interrogate a very large number of earth based sensors. AGIPA locates an array in space but locates all of its beam forming and beam steering network on the ground; thereby providing multiple high gain beams to be formed with minimal complexity in space. AGIPA offers: * Less total system cost by placing a high gain array on a central data collection system and reducing the cost of each of the thousands of sensors. * Rapid data collection due to electronic beam steering as well as through formation of multiple beams. * Nulling of unintentional RFI that can disable the entire data collection system.
    • Multibeam Adaptive Array for RPV Antijam Communication

      Noji, T. T.; Schwartz, L.; AIL (International Foundation for Telemetering, 1975-10)
      An application using a multibeam adaptive array for the simultaneous communications of command control, and telemetry data from 20 Remotely Piloted Vehicles (RPV's) to a command station is investigated. It is assumed that the RPV's are on tactical mission beyond FEBA as typically shown in Figure 1, and that communication links must be established to and from each RPV in the presence of many airborne and/or surface based jammers. The RPV's are assumed to be on data collection missions out to a maximum range of 100 km and must data link the sensor information (including digitized video of 20 Mbps) back to the tactical RPV control center. The data link will be operated at C-band. Other system parameters are summarized in Figure 2.
