A design tradeoff study of a telemetry system has been conducted for application to the Ranging Array using Thin Line Array technology. The study addressed electrical and mechanical interface requirements and considered commonality with other anticipated array developments. The overall objective of the Thin Line Array program at NUSC is to develop a high performance, reliable acoustic array at moderate cost which can be deployed from a submarine or a surface vessel with a minimum of handling equipment, and which will acquire data used to detect, classify, and locate adversary submarine activity. The objective of the subject program is to perform preliminary engineering tasks to validate concepts of telemetry functions for thin line-type arrays on monolithic chips. This study is performed as a system engineering task to insure that the telemetry configuration is compatible with the overall system requirements and to provide interface and packaging information. The study results are intended to guide the actual design and breadboarding of signal conditioning and digital multiplexer functions of the telemetry unit.
