Spatially Waveform Diverse Radar: Perspectives for High Frequency OTHR
2007 IEEE Radar Conference, 2007The application of multi-input multi-output (MIMO) radar concepts to HF over-the-horizon radar is considered to improve radar timeline management flexibility and to permit adaptivity on transmit. MIMO radar concepts in the literature are inconsistent and in this paper the taxonomy of MIMO radar is clarified and distinctions between different MIMO radar

Ocean-clutter model for high-frequency radar
IEEE Journal of Oceanic Engineering, 1991The time-varying behavior of ocean-clutter signals is investigated with the objective of clutter suppression for target detection. It is shown that the ocean clutter may be adequately modeled with two narrowband Bragg signals with time-varying frequencies. Low-order adaptive-prediction filters can thus be used to suppress the ocean clutter.

Maritime Surveillance Using Multiple High-Frequency Surface-Wave Radars
IEEE Transactions on Geoscience and Remote Sensing, 2014In the last decades, great interest has been directed toward low-power high-frequency (HF) surface-wave radars as long-range early warning tools in maritime-situational-awareness applications. These sensors, developed for ocean remote sensing, provide an additional source of information for ship detection and tracking, by virtue of their over-the ...

REENTRY PHENOMENA OBSERVED USING HIGH-FREQUENCY RADAR
1967Abstract : The Madre radar has been deployed in an over-the-horizon mode to study reentry phenomena associated with Athena-boosted reentry experiments at the White Sands Missile Range and with reentering manned earth satellites of the Gemini type. Preliminary results indicate the feasibility of using hf radars for over-the-horizon detection of reentry ...

High Pulse Repetition Frequency Pulse Doppler Radar
2012Pulsed radars that are not required to be Doppler sensing systems have traditionally employed low pulse repetition frequency (PRF) waveforms. A low PRF is defined as one which is sufficiently low so as to avoid range ambiguities. To avoid range ambiguity, the maximum detection range of the radar for all target and clutter returns is required not to ...
