Agenda • Mike Kurdziel • Introduction • About Harris • Software Defined Radio background • Hiro Sasaki • Example SDR architecture • The Soldier Personal Radio (SPR) • Jay Engert • The soldier’s perspective • All • Demonstration
Biography • Joined Harris Corporation RFCD in 1992 • Secure communications systems design • Design of encryption, key management and authentication systems and algorithms • Sr. Engineering Manager, Defense Systems Architecture (DSA) Group, for Harris Corporation • Education • BS (1986), MS (1988) and PhD (2001) in Electrical Engineering from the SUNY at Buffalo • 13 patents, and 2 patents pending • Authored/coauthored 15 publications on Military Communications • “Professional Engineer” (License No. 069432) in the State of New York since 1992
Introduction • Military communications objectives are complex and dynamic • Communications need to adapt to changing needs • “Software Defined Radio” evolved to meet this challenge • This presentation will provide an overview of a typical military radio product followed by a hands-on demonstration of a Harris radio communications system
Harris Corporation Business Segments RF Communications Tactical and land mobile radios, systems and networking apps for global Defense, Security and Public Safety markets Government Communications Systems Technology and systems integration for Defense, National Intelligence and Federal/Civil markets Integrated Network Solutions IT services, managed services, cyber integration, and media solutions supporting Government, Energy, Healthcare, Broadcast and Enterprise networks
RF Communications Division Tactical Communications Public Safety & Professional Communications International U.S. Department of Defense • Tactical radio products and integrated systems • JTRS-approved; delivering the JTRS promise today • Leading the transformation from narrowband to wideband networking • Tactical ISRproducts and applications • Communications Security products • Full range of Land Mobile Radio products • Integrated IP-based communications systems • Advanced 4G/LTE broadband communications systems
Software Defined Radio Modern military radios are essentially software processes and applications running on specialized computing platforms
SDR Advantages • Elimination of analog hardware and associated cost • Simplification of radio architectures and improved performance • Hardware specific components are replaced by DSPs and FPGAs • A family of radio “products” can be implemented using a common platform architecture • New products can be more quickly introduced into the market. • A common radio platform for multiple markets significantly reduces logistical support and operating expenditures • Software can be reused across radio "products” • Can reduce development time and cost dramatically • Allows "bug fixes" to be installed in the field • New features and capabilities can be added without significant cost • Software can compensate for problems in other areas of the system. • Ability to receive and transmit various waveforms using common hardware • Important for coalition interoperability
Anatomy of a Tactical Radio • Frequency Range • HF (2-30MHz): Long-range (up to 4000 km) • VHF (30-108MHz): Short range ground tactical (up to 50 km) • UHF (225-400MHz): Air-Air and Air-Ground (up to 300 km) • UHF SATCOM (280-320MHz): Worldwide • Wideband Networking (225-2000 MHz): Ranges up to 10 km • Modes of Operation • Voice (push-to-talk) • Data • IP point-to-point data • IP sub-network data • Radio Types • Handheld radios • Manpack / vehicular radios • Soldier radios • Key Fill • DS-101 EKMS • Sovereign/Coalition • Waveforms • US (MIL-STDs) and NATO (STANAGs) interoperable waveforms • Proprietary Harris exportable waveforms • Fixed frequency and anti-jam frequency hopping waveforms • Falcon II/III Radio Platforms • JTRS/SCA SDRs • Exportable SCA-based SDRs • Proprietary SDR • Information Assurance • Programmable INFOSEC • COMSEC • TRANSEC • Software Defined Radio IA
Biography • Joined Harris Corporation RFCD in 2003 • Started in Systems Engineering • Advanced in various roles in Program Management and Business Development • Product Manager of the Soldier Personal Radio (SPR) • Education • BS (2003) in Computer and Systems Engineering from RPI • MBA candidate at the University of Rochester’s Simon School of Business • Authored several defense industry articles related to Intelligence, Surveillance and Reconnaissance (ISR) technology
Example SDR Architecture Soldier Personal Radio (SPR)
SPR Functions • Red I/O Processor • General Purpose Processor • GPS Interface • Data Capture • Red Side Control • Digital Signal Processor • Crypto Interface • Audio Processing • Data Processing • Black I/O Processor • Waveform (Over the Air Protocol) • Modem (Converts data to RF) • Crypto Control • RF Interface • RF Front End • Antenna • Amplifier • Mixing • Matching, etc. • Audio and Data Ports • Embedded PDA (Leader Radio)
SPR Leader Radio Similar to Team Radio, plus: PDA in the Radio! Applications Processor Windows CE 5.0 Graphical Display Output Via Connector (e.g. head mount display) USB Host Port For external equipment (e.g. camera) RS-232 Port Serial network connection (PPP) Secondary Audio Interface For long-range Radio (retrans) Advantages of ‘PDA’ embedment: • Fewer devices to carry (reduced weight) • Reduced battery management • Tight integration of applications and radio
Biography • Joined Harris Corporation RFCD in 2003 • Started in Technical Training • Advanced in to roles of Application Engineer and Engineering Specialist • Product Specialist for the Soldier Personal Radio (SPR) • Served as a Career Airman in the US Air Force from 1982 to 2002 • Tactical Air Control Party (TACP) and • Close Air Support (CAS) • Deployments • Desert Storm for 8 months (Received Bronze Star) • Bosnia for 6 months • Kosovo for 6 months • Retired honorably at the rank of Technical Sergeant
TACP (Early Days) Tactical Air Control Party (TACP) Close Air Support (CAS)
TACP (Early Days) • To perform a standard CAS mission, we needed to talk to several groups for coordination, requiring numerous radios and COMSEC devices • Ground Commander • Intel • Artillery • Air Defense • ASOC (Air Support Operations Center) • Aircraft supporting the current mission • Equipment Needed • 1 x PRC-77 (VHF/FM Voice to talk to Army counterparts) • 2 x PRC-113 (VHF/UHF/AM Voice to talk Fast movers and Helicopters) • 2 x KY-57 (To Secure voice on VHF/UHF/FM Radios) • SATCOM (If we were lucky, we got a SATCOM channel, usually HF) • 1 x PLGR (GPS Military Grade) • 1 x PRC-104 (HF/AM for long range voice) • 1 x KY-99 (To Secure voice on HF radio)
TACP (Early Days) GPS SATCOM 2 x VHF/UHF/AM HF/AM VHF/FM 2 x KY-57 1 x KY-99
TACP (Present Days) = Multiband 117G HF PRC-150
