Ionospheric Clutter Suppression in HF Surface Wave Radar

Journal of Electromagnetic Waves and Applications, 2009
The ionospheric clutter has been proved to be one of the dominant clutters degrading the performance of the HF surface-wave radar (HFSWR) severely, so suppressing the ionospheric clutter is a vital part of radar signal processing sequence. In this paper, the spatial characteristics of the ionospheric clutter in a planar array are analyzed, then a new ...

Vessel Target Monitoring with Bistatic Compact HF Surface Wave Radar

IGARSS 2020 - 2020 IEEE International Geoscience and Remote Sensing Symposium, 2020
Compared with transmit/receive (T/R) monostatic High-frequency surface wave radar (HFSWR), the T-R bistatic HFSWR has the advantages of flexibility, receiver concealment and large coverage because of the separation between the radar transmitter and receiver locations.

Iceberg tracking using HF surface wave radar

Oceans '97. MTS/IEEE Conference Proceedings, 2002
An iceberg surveillance experiment involving multiple sensors was carried out in a one-week period between April and May, 1995. Several Canadian and U.S. Agencies and members of industry participated The Canadian Department of National Defence, in collaboration with industry provided high-frequency surface-wave radar (HFSWR) sensors, while the Canadian

HF surface wave radar operation in adverse conditions

2003 Proceedings of the International Conference on Radar (IEEE Cat. No.03EX695), 2004
For the past 12 years the Canadian Department of National Defence and Raytheon Canada Limited have collaborated on a cost-shared programme to develop an Integrated Maritime Surveillance (IMS) system based on HF Surface Wave Radar (HFSWR). The primary objective behind the programme was to demonstrate the capability of HFSWR to continuously detect and ...

Surface wave HF radar simulator

Radar Systems (RADAR 97), 1997
A computer code is described which has been developed for the simulation of surface wave high frequency (SW-HF) radar. The aim is to investigate the problems related to the detection and tracking of surface targets at beyond the horizon ranges. In SW-HF radar target detection involves stochastic features such as target RCS fluctuations, atmospheric ...

Design of reconfigurable receiver for HF surface wave radar

10th IET International Conference on Ionospheric Radio Systems and Techniques (IRST 2006), 2006
The paper describes the design of receiving system for short-range high frequency surface wave radar, which employs monopole/cross-loop antenna (one monopole and two cross-loops). The frequency synthesis of system is provides by two DDS chips, whose working clock comes from the same clock source.

Improved correlation detector for HF Surface Wave Radar

2011 IEEE RadarCon (RADAR), 2011
The challenge in HF Surface Wave Radar (SWR) lies in the detection of a target signal in the background of a strong sea clutter. An improved detector is presented which uses the property that the cut of sea clutter power along the azimuth axis is correlated over neighboring Range Doppler cells.

Results of a bistatic HF radar surface wave sea scatter experiment

IEEE International Geoscience and Remote Sensing Symposium, 2003
We describe a set of HF radar sea scatter experiments that test a new digital receiver in both monostatic and bistatic modes. The University of Miami's OSCR HF radar system was used as a transmitter signal source, and sea echoes were received with both receive systems using different receive antenna arrays.

An estimation and verification of vessel radar-cross-sections for HF surface wave radar

2003 Proceedings of the International Conference on Radar (IEEE Cat. No.03EX695), 2004
The radar cross sections (RCS) of both small and large ships for High Frequency Surface Wave Radar (HFSWR) were studied by using Numerical Electromagnetics Code and by using measurements from a HFSWR system at Cape Race, Newfoundland, Canada. The results of the study indicate that Teleost, a 2405-ton Canadian Coast Guard ship, and large cargo-container
