| dc.description.abstract | Communication plays a crucial role in the context of military operations. The
Revolution of Hand-Held radio from Analogue to Digital Technology reached up to
many advanced radios with the application of Modern Technology. A famous means
of communication which is utilized in modern military warfare is Digital Mobile
Radio (DMR). However, due to highly expensive DMRs, it cannot be easily catered to
suit various requirements. This paper aims to discuss the first Hand-Held DMR
designed and developed for the Sri Lanka Military named the Creeper (The unique
bird who can sing vast frequency bands). Creeper aims to reduce the capital cost
investment on expensive DMR and provide flexibility for future improvements. The
Creeper DMR is checked against existing DMRs such as Racal Cougar, tested on the
field, and many improvements were made. A Voice Coder (Vocoder) is used to meet
the VHF frequency bands designed and then further developed to work on both VHF
and UHF bands. The test results were satisfactory in the field and it is currently being
used by Tri-services in Sri Lanka. Creeper has successfully provided a cost-effective
solution and would stand out as possible future foreign market. | en_US |
