D.mustuseinformationfromtargetsforwardof

thebeam雷达定位主要测量目标的距离和角度。通过测量发射信号和目标反射的回波信号之间的时间差，将时间差除以2，再乘以光速，就可以得到目标到雷达的距离。目标相对雷达来说，来自哪个方向，主要测仰角和方位角，主要是通过雷达天线的方向性实现的，雷达发射的波束像探照灯的光柱一样，窄窄的，方向性很强，照到哪个方向上看有没有目标的回波，没有就换个方向，有的话就记下角度，所以雷达天线在不停的换方向、扫描，以实现大空域的探测覆盖。有了距离和角度，就可以知道目标相对雷达位置，从而实现定位。50.______isdesignedtoraisethealarm报警ashoreinreactionto回应securitythreats威胁orsecurityincidents事件bynotifyingtheflagState船旗国oftheshipwithoutalertingshipsorcoastalStatesinthevicinity附近orgivinganyindicationonboard.
