Features

  • Enables car manufacturers to meet NCAP R79 safety requirements using a single chip radar sensor
  • Provides unmatched corner radar performance with best in class RF performance enabled by a fourth transmitter for 33% higher angular resolution than traditional 3 transmitter devices
  • Detect and track objects (such as cars and trucks) up to 200 meters away with velocity of ±140 kilometers per hour (kmph)
  • Antenna azimuth field of view ±80º with azimuth angular resolution of approximately 9.5º
  • Demonstrates the following AWR2994 capabilities:
    • TX phase shift
    • Data compression
    • HWA with Doppler division multiple access (DDMA) processing chain provided by mmWave SDK
  • Builds customer confidence on mmWave device capabilities
  • Improves the customer development cycle (for example, hardware redesign and software effort)
