ARW-3401 is a HW/SW configurable wideband signal reception platform that provides various COMINT functionalities/features. Modular architecture of ARW-3401 allows it to be configured as ​

    Single channel fast tuner,
    Multi channel coherent/independent fast tuner,
    Surveillance/Monitoring receiver with multichannel DDRs.

ARW-3401 with its various configurations is enough to provide full backbone of a COMINT/DF system.  As a key equipment in a-SMARD (ASELSAN Surveillance, Monitoring and Radio Direction Finding Family), ARW-3401 is suitable for fixed, land mobile, naval, airborne platforms.

Fast tuning speed, compact size, exceptional environmental, RFI/EMI specifications of ARW-3401 best suit military/professional applications in challenging RF spectrum crowded by state-of-the-art communication emitters.
