UNMANNED SYSTEMS UPDATE

24 Jun 10. OEwaves performed a study based on its unique microwave photonics technologies, when combined with conventional RF technologies, to investigate the feasibility of deploying a miniature GTMI radar system on the WASP UAV. Using Whispering Gallery Mode (WGM) optical resonator technology, OEwaves developed and demonstrated a transmit/receive capability that is small in size and weight, consistent with the GMTI Radar parameters required to enable detection of slow moving personnel and material, and compatible with the power availability payload capacity of the WASP UAV. The findings of this study will support development of a future DARPA program addressing this need. OEwaves’ unique microwave photonic technology simplifies the architecture of conventional microwave techniques by addressing the critical need to substantially reduce its size and power requirements. This is accomplished through the patented technology of ultra-high quality factor crystalline whispering gallery mode optical resonators. Based on the previously demonstrated use of WGM resonator in a monopulse receiver configuration, this one-step photonic mixing, combined with the small bandwidth of the miniature resonator and the photodetector, eliminates the multiple steps of mixing and filtering required in conventional super heterodyne receivers.

18 Jun 10. Turkey’s six Heron drones, located at an air base near Turkey’s Iraqi and Iranian borders, have stopped flying, after Israeli operators left the base due to Turkish-Israeli tensions. Turkish Defence Minister Vecdi Gonul told the Anatolia News Agency that Turkish personnel would soon begin operating the Herons. Turkish personnel were trained in Israel to operate the drones and have operated the UAVs in Turkey since their delivery, according to Gonul. Turkey-Israeli political relations have been strained since Israeli commandos raided a Turkish-led aid flotilla bound for the Palestinian Gaza Strip on 31 May 2010, killing nine Turks. Turkey received the six Herons in April from Israel Aerospace Industries and Elbit as part of a $188m contract signed in 2005. (Source: airforcetechnology.com)
