摘　　要：利用雷达探测技术,以绑有水葫芦的标准泡沫板为目标物,系统研究了水浮植物雷达对水葫芦目标识别能力、探测范围以及距离、面积、速度测量性能。试验结果表明:水浮植物雷达可以区分水面、墙体以及水葫芦,径向探测距离为37~114.5 m,不同径向距离的平均测距误差均在0.6%以内。在雷达3°/s扇扫速度小范围扇扫模式下,远距离比近距离面积测量平均误差高26.99% 同一距离,12°/s比3°/s扇扫速度的面积测量平均误差低12.13%。另外,在0.1~1.0 m/s的目标速度测量范围内,雷达对水葫芦的测速均方误差百分比不超过8%。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.
