A general purpose software system for applications in different fields of physics
(NATO. SACLANTCEN, 1979/12)The paper presents the principle of a software system (FTSS) developed by the Danish Defence Research Establishment (DDRE) for applications in different fields of physics. Software is made up by independent modules exchanging ... -
SACLANTCEN real-time signal processing system
(NATO. SACLANTCEN, 1979/12)To meet its increasing requirements in real-time signal processing, SACLANTCEN has developed a general purpose. signal processing system called WARP to be uS.ed with a fairly wide range of underwater acoustic research ... -
System functional migration: high-level language to hardware
(NATO. SACLANTCEN, 1979/12)This paper intends to examine system functional allocation among available processing resources in a systematic way. The discussion will focus first on the criteria for assigning functions to processors, that is, horizontal ... -

(NATO. SACLANTCEN, 1979/12)At the Defense Research Establishment Atlantic Dartmouth, Nova Scotia, Canada a data aquisition sytem been engineered to monitor and beamform data from element line arrays. This system has been designed to with either towed ... -
Experience with a MAP 300 array processor
(NATO. SACLANTCEN, 1979/12)The paper is a summary of the experience collected during almost two years of programming a CSPI MAP 300 array ' processor in signal processing applications. After a short overview of the most interesting features of SNAP ... -
Signal-processing language and operating system
(NATO. SACLANTCEN, 1979/12)Signal Processing Language/One (SPL/I) was developed at the Naval Research Laboratory (NRL) as a high-level computer programming language for signal processing. SPL/I is the first high-level language to be designed for ... -
Display techniques
(NATO. SACLANTCEN, 1979/12)This paper sets out to review current sonar information displayc and to indicate how technological advances over the past decade lead to the concept of a common information display console. To appreciate the problems ... -
Using intelligent graphics terminals in real-time processing
(NATO. SACLANTCEN, 1979/12)At the Naval Research Laboratory intelligent graphics terminals are being utilized for real-time acquisition, storage, processing and display of oceanographic data when mini-computer systems are inappropriate. The intelligent ... -
A micro-programmable correlator for real-time radar processing
(NATO. SACLANTCEN, 1979/12)This paper presents a novel design of a multibit, digital correlator for incoherent scatter radar observations. By utilizing bit-slice microprocessor elements and internal control by microcode instructions, a high-speed ... -
A modular approach to signal processing
(NATO. SACLANTCEN, 1979/12)This paper outlines work in progress on modular systems for beamforming and signal processing. The modules described were developed using commercially available digital L.S.I circuits and the emphasis during development ... -
