| 摘 要： | 以包覆细铜纱网的乒乓球作为标准检测目标，检测了X-频带，波长3cm的公主岭昆虫雷达观测空中飞行昆虫的有效距离。检测到乒乓球回波的最远距离为5185.6m；计算观测个体粘虫Mythimnaseparata（Walker）的最远有效距离约为2000m，观测个体褐飞虱Nilaparvatalugens（Stal）的最远有效距离的为300m。该雷达适于观测粘虫等体重几十mg的昆虫在空中的飞行动态。

| Abstract: | The measurement of available distance observing airbone insect by a entomological radar, Gongzhuling entomological radar at X-band and wavelength of 3 cm, was carried out in northeastern China in 1991. The result showed a reliable maximum rang of delection for a 16 cm2 calibration target (copper-plated ping-pong ball) of 5185.6 m. It was capable of detecting individual armyworm moth Mythimna separata (Walker) at distances of up to 2 km and brown planthopper, Nilaparvata lugens (Stal) at distance of up to 300 m, and concentrations of insects at greater range by Gongzhuling entomologlcal radar. It was available that this radar was applied to observe some insects weighing tens milligrams. |
