Maritime over the Horizon Sensor Integration: High Frequency Surface-Wave-Radar and Automatic Identification System Data Integration Algorithm [PDF]

open access: yesSensors, 2018
To obtain the complete operational picture of the maritime situation in the Exclusive Economic Zone (EEZ) which lies over the horizon (OTH) requires the integration of data obtained from various sensors. These sensors include: high frequency surface-wave-

MIMO Radar Ambiguity Properties and Optimization Using Frequency-Hopping Waveforms [PDF]

open access: yes, 2008
The concept of multiple-input multiple-output (MIMO) radars has drawn considerable attention recently. Unlike the traditional single-input multiple-output (SIMO) radar which emits coherent waveforms to form a focused beam, the MIMO radar can transmit ...

The AN/FPS-118 OTH Radar: Chapter 5, OTH Handbook. [PDF]

open access: yes, 1996
Abstract : This report familiarizes the radar operators with the radar features used in the daily operation of the radar. These consist of the radar layout, its sector-segment arrangement, the barrier and interrogation beams, the ionospheric model residing in the radar system, and various displays available in the important missions of Correlation and ...

A Modified Sequential Multiplexed Method for Detecting Airborne and Sea Targets With Over-the-Horizon Radar

open access: yesIEEE Access, 2020
Phased array over-the-horizon (OTH) radar usually needs to detect sea target and airborne target in different directions. Conventionally, the sea target and airborne target are detected sequentially with the coherent integration completely accomplished ...
