补充资料:超视距雷达
超视距雷达 over-the-horizon radar 工作在短波波段,能监视地平线以下目标的地面雷达。按电磁波传播方式,可分为天波超视距雷达和地波超视距雷达两类。前者利用电离层折射,后者利用地球表面绕射。而天波超视距雷达又可分为前向散射和后向散射两种类型。天波前向散射雷达的发射站和接收站相距数千千米,利用目标对电离层的扰动来探测目标,必须多站配置才能求得目标距离,现已极少采用。天波后向散射雷达和地波超视距雷达的发射站及接收站均位于邻近地点,利用目标后向散射原理探测目标,可提供目标方位、距离和径向速度。天波后向散射雷达能探测地面距离为900~3500千米的低空目标。地波超视距雷达必须架设在海岸边,以减小传播损耗,对飞机的作用距离可达200~400千米。超视距雷达一般采用方位电扫±30°的相控阵天线,用单脉冲比幅法测角,用多普勒信号处理技术完成动目标检测。天波后向散射雷达是低空防御系统中一种有效的预警手段,是超视距雷达发展的重点。超视距雷达还能进行海洋状态的遥测及空中交通管制。 |
