Air Route Surveillance Radar Version 4 (ARSR-4)

This radar system monitors air traffic between airports and across the country with an effective range of 250 nmi. TSC has supported this system in the following ways:

  • Analysis of antenna structure on Mode S pattern
  • Identified incremental benefits of monopulse and selective addressing
  • Radiation hazard assessment
