A Low SWaP-C Chirped LFMCW Radar Based UAS Collision Avoidance System Navy SBIR FY2015.1 Sol No.: Navy SBIR FY2015.1 Topic No.: N151-026 Topic Title: A Low SWaP-C Chirped LFMCW Radar Based UAS Collision Avoidance System Proposal No.: N151-026-0875 Firm: Intelligent Fusion Technology, Inc 20271 Goldenrod Lane Suite 2066 Germantown, Maryland 20876 Contact: Genshe Chen Phone: (240) 481-5397 Abstract: The proposal presents a low space, weight and power (SWaP) and low cost chirped linear frequency-modulated continuous-wave (LFMCW) radar based UAS collision avoidance system. A novel radar structure is applied to make the system having enough working range and at the same time having high enough range and angle estimation accuracy. The smart antenna technique is applied, so one transmit can be used to search all interested angles with a gated range. The software defined radio (SDR) concept is applied to make the system having the plug and play capability. The system integrates a mixture of state-of-the-art modeling and algorithms, such as range gated chirp radar receiver, and a lot of mature techniques, such as smart antenna angle estimation, Fast Fourier transform (FFT) for target detection, Commercial off-the-shelf (COTS) parts, etc. This combination of the state-of-the-art techniques and mature techniques/devices greatly reduces the system implementation risk. Benefits: : The proposed Chirped LFMCW Radar Based UAS Collision Avoidance System can be applied to various military UAS (group 2/3 or larger). We already have close connections with DoD and industry communities. The market for military is quite large and IFT has successfully transitioned research prototypes for inclusion in DoD contractor research simulations. This technology can also be directly applied on passenger aircraft, such as Boeing series and Airbus series, for collision avoidance. 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.
