A Low SWAP High Precision Spectrum Monitoring System with Calibrated Antennas Navy SBIR FY2014.2 Sol No.: Navy SBIR FY2014.2 Topic No.: N142-114 Topic Title: A Low SWAP High Precision Spectrum Monitoring System with Calibrated Antennas Proposal No.: N142-114-0696 Firm: Intelligent Fusion Technology, Inc 20271 Goldenrod Lane Suite 2066 Germantown, Maryland 20876-4104 Contact: Genshe Chen Phone: (240) 481-5397 Web Site: http://www.i-fusion-i.com/aboutus/overview.htm Abstract: This proposal presents a low SWAP spectrum monitoring system covering from 100MHz to 14GHz. The system sensitivity is -120dBm with 1kHz bandwidth. It has a SWAP of 10cmx12cmx1.5cm, 2lB, and less than 2.8W. It is much smaller than any available USB spectrum analyzer plus a small PC. The system divides the covered frequency band (100MHz ~ 14GHz) into three sub-bands (sub-band I - 100 ~ 800MHz, sub-band II - 0.8 ~ 7GHz, sub-band - III 7 ~ 14GHz) and each sub-band is covered using a set of antennas (three same antennas for DOA estimation) and the following receivers. The two higher frequency sub-band antenna sets are fixed relatively to each other (each set will be on one PCB board) and lower frequency sub-band antennas are installed on ScanEagle wings and fuselage (there may be some errors due to installation and wing shape change in flying, but it is tolerated for the relative large wavelength). The micro-controller will select which sub-band will work and what frequency signal will be collected. At any time, the system only works on one sub-band, and the other two are turned off to save power. The DOA estimation capability is for precise EM signal power measurement. Benefits: The proposed Low SWAP Spectrum Monitoring System has tremendous application potential in many military applications. It can be used for EM propagation channel measurement, Radar or communication sources detection and localization on the battle field. It can be applied on small UAV for battle field monitoring or CubeSat for monitoring the region with A2AD capability and also detecting and monitoring potential space-based threats. We already have close connections with DoD and industry communities. The market for military is quite large and IFT has successfully transitioned research prototype for inclusion in DoD contractor research simulations. We also recognize commercial application of this project with the concepts being developed. The proposed system can be directly used in telecom industry for lower cost and fast field measurements for cellular system base station antenna site selection and also EM environment monitoring for undesired sources detection. IFT has a business model of product design and marketing for small-scale solutions, partnering with prime contractors for system delivery, and/or service contracts for technical solutions during operational support. As soon as we receive the Phase I award, we will begin this commercialization process. We will sign a non-disclosure agreement with potential partner companies, such as Raytheon, discuss certain royalty issues, and discuss marketing issues. When the Phase II prototype is finished and fully tested, Phase III commercialization can immediately be started. For near- and mid-term, our proposed system can be directly used in projects like Trident Warrior needing EM propagation measurement/verification. The propose system is low SWAP and can connect with other unit via communication port, thus it can be used with like LADAR, weather station, etc. on a ScanEagle or larger UAV. Return
