• AN IMPROVED METHOD FOR SYNCHRONIZING MULTIPLE TM FILES

      Terrien, Ron; Endress, William; Raytheon Missile Systems (International Foundation for Telemetering, 2016-11)
      In a previous paper “Merging Multiple Telemetry Files From Widely Separated Sources For Improved Data Integrity” presented at the 2012 ITC\USA conference, a method for synchronizing TM files at the minor frame level was presented. This paper expands on that work by describing a method for synchronizing the files at the minor frame level faster and at the earliest frame possible using an internal counter. This method is also useful if the minor frames fall out of sync due to large dropouts.
    • Frequency Partition Techniques of FMCW Radar Imaging Systems for MIMO Multi-Static Array Modality

      Lee, Hua; Thornton, Matthew; University of California (International Foundation for Telemetering, 2016-11)
      The modalities of many imaging applications have been advancing toward the MIMO format for improved efficiency. This paper presents an approach to the implementation of the MIMO operating modality for FMCW radar imaging systems with multi-element data-acquisition arrays. The unique characteristics of the software-defined step-frequency FMCW imaging systems enable the simple and precise orthogonalization procedure through direct spectral partitioning. This paper includes the description of the data-acquisition hardware of an eighttransceiver radar imaging system, imaging formation algorithms, MIMO implementation, and results of laboratory experiments.
    • AN INITIAL LOOK AT ADJACENT BAND INTERFERENCE BETWEEN AERONAUTICAL MOBILE TELEMETRY AND LONG-TERM EVOLUTION WIRELESS SERVICE

      Temple, Kip; Air Force Test Center (International Foundation for Telemetering, 2016-11)
      With National Telecommunications & Information Administration (NTIA) Advanced Wireless Services (AWS-3) auction of frequencies in the 1695-1710 MHz, 1755-1780MHz, and 2155- 2180MHz bands, users of the Aeronautical Mobile Telemetry (AMT) band from 1755- 1850MHz, known as Upper L-Band, could be greatly affected. This paper takes an initial look at how the 1755-1780MHz band will be used by the cellular carriers and presents some preliminary testing results of adjacent channel (band) interference that could be experienced by AMT users. This paper should be considered as the stepping off point for future interference discussions, required analysis, and further testing.
    • HOW TO MAKE A RUGGEDIZED SSD

      Budd, Chris; SMART High Reliability Solutions (International Foundation for Telemetering, 2016-11)
      SSDs are now commonplace in all types of computing from consumer laptops to enterprise storage systems. However, most of those SSDs would not survive in environments with extreme temperatures or high shock and vibration such as found in embedded and military systems. The problems in this space are more than just mechanical; they involve all aspects of the design including electrical and even firmware. A combination of all three engineering disciplines is needed to provide a robust ruggedized SSD product.
    • Spectrum Access R&D (SARD) Program: Conformal C-Band/Multi-band Antenna Project

      Kujiraoka, Scott; Fielder, Russell; Apalboym, Maxim (International Foundation for Telemetering, 2016-11)
      The Conformal C-Band/Multi-band Antenna project will support the AWS-3 auction by providing the technology to integrate C-Band or multi-band telemetry(TM) antennas on test articles such as missiles, weapons, or aircraft. These test articles would then provide C-Band or multi-band TM data to ground station receivers that are relocated to the C-Band frequency range through the AWS-3 Spectrum Relocation Fund program. This project would advance the technology of antennas in the C-Band region for test article TM integration. Successful use of C-Band and Multi-Band antennas for aeronautical mobile telemetry (AMT) on test and training ranges is dependent on the advancement of key technologies. This paper will detail the technology areas being matured by this project as well as the capabilities to be demonstrated.
