Abstract


High-Frequency Surface-Wave Radar (HFSWR), utilizing vertically polarized Electromagnetic Wave (EMW) that travels along the air-water interface with low propagation loss on high conductive ocean surface, can detect and track the targets beyond the horizon such as vessels on the sea and aircrafts at a low altitude; and it provides a new technique for the resource management and exploration of the Exclusive Economic Zones (EEZ) to those coastal nations.A novel radar system, the coast-ship bistatic/multistatic HFSWR, has some advantages on stealth, maneuverability and flexibility over the conventional coast-based or shipborne HFSWR. The radar employs the transmitting arrays mounted sparsely along the coast to radiate energy and only one receiving antenna mounted on a ship to collect signals based on synthetic impulse and aperture (SIA) technique.In this paper, the principle and basic signal processing flow of this radar is first introduced, and what follows is a performance analysis of Frequency-Modulated Interruptive Continuous Wave (FMICW). The electromagnetic environment of the radar and the propagation characteristics of HF EMW are studied in the next section. The author is concentrated on the characteristic of first-order and second-order sea clutter under the condition of bistatic configuration and moving receiver platform, including first-and second-order peaks distribution, space-time distribution for transmitting bearing. The theoretic analysis is examined with the experimental data, and the reasons resulting in the difference between the theoretic and experimental conclusion are analyzed. At last, a summary is given, and some problems encountered probably in the further works and potential solutions to these problems are also discussed.
