Features & benefits

Reliable and flexible echo generation

  • Install up to four different, customer defined fixed delay lines to simulate unrelated object echoes
  • Simulate echoes with minimum delay for short range radar (SRR) sensor tests
  • Simulate echoes for long range radar (LRR) sensor tests
  • Select additional Doppler offsets to simulate radial velocity for each artificial object individually or for all artificial objects together

Open Lightbox

With the R&S®AREG100A it has never been easier to monitor the quality of automotive radar sensors in mass production.

Test today’s and tomorrow’s radar sensors

  • Choose a 24 GHz ISM band frontend, an E-band frontend or both together for sequential operation
  • Profit from a future proof wideband E-band frontend with 4 GHz instantaneous bandwidth for short range radar (SRR) sensor test
  • All frontends in a single antenna configuration for superior MIMO testing performance or in a two antenna configuration with high RX/TX isolation for lowest ringaround.

Open Lightbox

R&S®AREG100A with single antenna frontend for reliable testing of MIMO radar sensors

Ready for RED

  • Measure the sensor’s equivalent radiated isotropic power (EIRP) in line with the applicable standards with a connected R&S NRP8S(N) power sensor
  • Verify robustness of radar sensors against in-band interferers with a connected analog or vector signal generator
  • Measure occupied bandwidth and unwanted emissions with a connected signal and spectrum analyzer
