Clarinet Merlin Receiving System (CMRS)
CMRS is a ship-to-shore communications system that continuously monitors for transmissions from Submarine Emergency Communication Transmitter (SECT) buoys (AN/BST-1) launched from U.S. Navy submarines. This listening network provides global coverage from six strategically based receive sites that are monitored simultaneously from the COMSUBFOR and COMSUBPAC Broadcast Control Authority(s) (BCA.
Long Wave Inc was awarded a SPAWAR contract, in June 2003, to upgrade the legacy Clarinet Merlin Communications System. The totality of this effort included the production, integration, testing, installation, documentation, and life-cycle maintenance of the entire CLARINET MERLIN system from the receiver sites to the BCA(s), including the operator interface/display.
Long Wave’s specially designed digital signal processor (DSP) based decoding unit is the nucleus of this vastly improved communications system. The Long Wave DSP decoder algorithms were specifically designed and optimized for improved performance within the HF Radio Frequency spectrum, providing a minimum of 10 dB improvement over the legacy system.
Long Wave’s CLARINET MERLIN receiving system is designed with a high degree of equipment redundancy and innovative automation features. Each receiver site has special self test software and hardware which automatically performs equipment self tests at regular intervals. In the event of a failure, the software automatically isolates the failed equipment, places the backup component in service, and then notifies the BCA operator of the equipment failure. Long Wave maintenance personnel are on 24-hour call to assist the BCA(s) with any maintenance related issues.
In addition to the shore based receive function; the CLARINET MERLIN receiving could be easily configured for aircraft applications, such as the TACAMO E-6B.
