Technological advancements over the years have increased the use of Radar technology in the field of robotics, especially in marine robotics to aid obstacle detection algorithms. Obstacle detection comprises of an analytical process in which different algorithms are applied to the field of study to determine the range of objects that are within the reach of a robot. Radar signal analysis and target...
The benefits of a commercial approach to the deployment of radar surveillance along the Great Lakes St. Lawrence Seaway System (GLSLSS) is discussed. Surveillance solutions must be multi-mission suitable, scalable, flexible, maintainable, upgradeable, interoperable, shareable, and affordable. This flexibility is fundamental to successfully leveraging tomorrow, investments made today in order to keep...
This document describes some design considerations for a modern naval fire control and tracking radar. The main purpose of this type of system is to track one, or sometimes a few, targets extremely accurately. Some of the basic design considerations have not changed considerably over the years, even if the solution is different due to e.g. increased processor capacity. This paper will briefly outline...
The work described in this paper is a continuation of previous analytical work that has progressed to an experimental phase. The paper discusses the development of an ultra-wideband (UWB), forward-scatter radar (FSR) system for the detection and (ultimately) automatic recognition of low reflectivity maritime targets. Here we present the concept, developed hardware and selected initial experimental...
Based on the legacy of marine radars, historical coastal surveillance sensors were based on the cheap magnetron-slotted waveguide antenna combination and were addressing sea-lane traffic control missions. New regulations in the marine world, such as the SOLAS convention, and increasing requirements for very small objects tracking, put new requirements on radar performance. It triggered an evolution...
A bistatic HF radar has been developed for application to ocean current mapping and ship vector tracking. The radar can operate in a multi-frequency mode, so that it can map ocean current vertical shear and can provide more robust ship tracks than single frequency HF radars. This tracking robustness is achieved by avoiding target fading due to echo nulls from frequency and azimuthal variations in...
Marine situational awareness is a key factor in coastal activities, e.g. national security (terrorism, drug smuggling, etc.) and environmental protection (marine protected areas, fishery monitoring and regulation, oil spills, etc.). HF surface wave radar is a strong candidate to become a component of any large area, vessel-monitoring network. We discuss estimating the primary metrics for assessing...
This paper addresses the method for automatic measurement of projectile target deviation using water columns cause by underwater explosion. The detection and tracking of water column is operated according to the transformation of RCS of a water column. A model of water columns is described here, and a bi-parameter sea-clutter map was used as detection background in order to distinguish water columns...
