| 摘 要： | 防空雷达为了消除从旁瓣进入的干扰,通常采用自适应旁瓣对消和旁瓣消隐技术。旁瓣对消主要消除从旁瓣进入的连续式杂波干扰;旁瓣消隐主要消除从旁瓣进入的脉冲式杂波干扰。旁瓣消隐技术在使用中存在的一个问题是:当从旁瓣进入的脉冲式杂波干扰充满整个距离通道时,旁瓣消隐器在抑制干扰的同时,也使目标信号被抑制,从而失去对目标的探测能力。提出了一种技术方法,可使二者合二为一,并可有效解决旁瓣消隐技术存在的问题,从而可使防空雷达有效消除从旁瓣进入的连续式杂波干扰和脉冲式杂波干扰。

| Abstract: | Self-adaptive side-lobe cancellation and side-lobe blanking technologies are usually adopted in air defence radar to eliminate interference from side-lobe.The former is mainly used to reduce continuous clutters while the latter for pulse-type clutters.One problem existing in side-lobe blanking is that when pulse-type clutters fill in the whole range channel,the blanker suppresses not only the clutters but the target signals as well,thus loses its detection ability.A combination of cancellation and blanking technology is proposed,which can not only settle the existing problems in side-lobe blanking but also enable the radar to effectively eliminate continuous and pulse-type clutters interference from side-lobe. |
