THE PERFORMANCE OF WATER HYACINTH DETECTED BY FLOATING PLANT RADAR

In this paper, a standard foam board tied with water hyacinth was set as the target, and the performance of the floating plant radar, including measurement target recognition, detection rang, distance, area and speed, was systematically studied using the radar detection technology. The results showed that floating plant radar could distinguish water hyacinth from water and wall. When the range of radial detection ranged from 37 to 114.5 m, the average ranging errors of different radial distances were within 0.6%. In small-area scan mode with radar sector-scan velocity at 3°/s, the average measurement error of area at long distance was 26.99% higher than that at close distance. At the same distance, the average area measurement error of radar sector-scan velocity at 12°/s was 12.13% lower than that at 3°/s. Meanwhile, the mean square error of radar velocity measurement for water hyacinth was less than 8% within the range of 0.1 m/s to 1.0 m/s.
