Abstract :
To improve the capability of high frequency (HF) surface wave radar to suppress interference, an adaptive anti-interference technique was evaluated by using subarrays in OSMAR2000 (ocean state monitor and analysis radar, manufactured in 2000). In this paper, we put forward a scheme to suppress the external HF radio strong interference based on OSMAR2000 radar without increasing any accessional facilities, and some radar experiments were carried out by using a monopole as main antenna and other three vertical monopoles as auxiliary antennas. This paper presented the results of a preliminary study of an adaptive system with subarrays for the suppression of strong interference. The results of the study show that the technique worked well against the observed interference.
