Adaptive normalization of active sonar data
(NURC, 2006/08)
In active sonar detection the background interference is reduced through normalization prior to applying a detection threshold. From the two mainstream normalization algorithms, i.e. the sliding window and the split window, ...
Doppler passive fathometry
(CMRE, 2019/05)
Passive fathometry is a technique whereby broadband ambient ocean noise received on an array of hydrophones is averaged and cross-correlated to produce a sub-bottom profile [Siderius, Harrison, and Porter (2006). J. Acoust. ...
Multiple sensor Bayesian extended target tracking fusion approaches using random matrices
(CMRE, 2019/06)
The tracking of extended targets is attracting a growing literature thanks to the high resolution of several modern radar systems. A fully Bayesian solution has been proposed in the random matrix framework. In this paper, ...
Localization of multiple sources using time-difference of arrival measurements
(CMRE, 2019/06)
This paper addresses the problem of localizing an unknown number of static sources emitting unknown signals from time-difference of arrival (TDOA) measurements. Based on the framework of random finite sets and finite set ...
Active detection enhancement in coastal areas
(NURC, 2006/08)
The processing chain used for active detection analysis in association with measures of performance that allow real time performance monitoring is presented. Real life examples demonstrating environmental volatility ...
The MPS-3 and the SPS-81
(NATO. SACLANTCEN, 1979/12)
The Larqe Aperture Acoustics Branch of the Naval Research Laboratory has developed a sea-qoinq signal processinq system in which two different types of array processors are used - a Signal Processing Systems SPS-81 and ...
Some high efficiency digital signal processing techniques for high speed signal processing systems
(NATO. SACLANTCEN, 1979/12)
Some high efficiency digital signal processing techniques, based on digital filtering are presented for real-time general-purpose, high-speed signal processing systems. At first high efficiency one-dimensional and ...
Overview of the ADPS signal processor
(NATO. SACLANTCEN, 1979/12)
Laboratory utilization of a standard signal processor
(NATO. SACLANTCEN, 1979/12)
The AN/UYS-l Advanced Signal Processor (ASP), or PROTEUS, is the U.S. Navy's standard signal processor and is being utilized in several systems. For shipboard use, the ASP is used as a processor with no peripherals, generally ...
Development of military ARGUS computers and MOD bus for close-coupled signal processing applications
(NATO. SACLANTCEN, 1979/12)
The next generation of Naval sonar systems will make extensive use of flexible programable modules to implement signal-processing algorithms. A number of UK Defence Establishments are engaged in a series of coordinated ...
