High-Frequency Radar in Coastal Areas Monitoring Systems
2021 Radiation and Scattering of Electromagnetic Waves (RSEMW), 2021The current approach to ensuring the necessary quality of marine activities relate to the assessment of the state of the ocean environment. The development of operational methods and instruments of observation, as well as the assessment of the state of the ocean and its forecast determine such approach.

Intelligent radar management techniques in high frequency surface wave radar
IET Seminar on Intelligent Sensor Management, 2007This paper has highlighted and provided some background as to why HFSWR has been a leader in intelligent radar techniques as without them the robust radar performance cannot be achieved. The use of basic Intelligent Radar Techniques has provided the ability for the radar to operate in a complex environment effectively and robustly.

Timing Signal Generator for High Frequency Radar
2020 IEEE 1st International Conference for Convergence in Engineering (ICCE), 2020In a radar application, Time Signal Generator (TSG) is used to generate timing and control signals which helps radar to operate in different functions. The functions include tracking, detection, and hold mode. Timing Signal Generator is the heart of radar applications.

High frequency radar cross section prediction
Digest on Antennas and Propagation Society International Symposium, 2003The essentials of a method developed to obtain the cross section of perfectly conducting targets by considering the surface current components induced on the bodies is presented. This approach treats the surface traveling wave phenomenon, allowing it to be included in RCS (radar cross section) computations for complex objects. >

Passive radar in the high frequency band
2008 IEEE Radar Conference, 2008Passive radar systems using emitters of opportunity for target detection and tracking have received significant interest recently, especially those which exploit frequency modulated (FM) radio stations and TV transmitters as signal sources. This paper is concerned with passive radar systems that utilize signal sources in the high frequency (HF) band (3-

High Frequency radar measurement resiliency with bistatics
OCEANS 2015 - MTS/IEEE Washington, 2015Increasing the resiliency of High Frequency radar measurements has been a priority within the community for the past several years. One method to increase resiliency is through the use of a bistatic radar configuration, which is unique to the SeaSonde HF radar.

Evaluation of high frequency radar wave measurement
Coastal Engineering, 1999Abstract The spatial coverage, temporal availability and spectral and parameter accuracy of wave measurements using radars operating at the upper end of the high frequency (HF) radio band are discussed. The two radars used are the Ocean Surface Current Radar (OSCR) developed in the UK and the Wellen Radar (WERA) developed in Germany. The measurements

Waveform analysis for high-frequency FMICW radar
IEE Proceedings F Radar and Signal Processing, 1991The paper describes the waveform analysis for an experimental long-range highfrequency radar system with a design capability for over-the-horizon detection of ocean surface targets up to 400 km from shore with a range resolution of 400 m. Motivated by the need to maximise the transmitter duty cycle in order to detect long-range targets, the radar is ...

Impulsive Interference Mitigation in High Frequency Radar
2006 1ST IEEE Conference on Industrial Electronics and Applications, 2006An effective method for impulsive interference mitigation in high frequency (HF) radar based on the detect-excise-and-extrapolate idea is presented. The key to the method's success is suppressing the ocean clutter in the time domain prior to detecting the impulsive interference.
