With this radar system and a specially trained Air Force crew the aircraft can operate at a low altitude and in night or adverse weather conditions.
有了这种雷达和经过特别训练的空军机组，飞机可以在很低的高度、夜间或不利的天气条件下飞行。
Unlike high altitude aircraft, helicopters aren't so vulnerable to being seen by radar, as they fly low and are often hidden by the terrain. The big issue is the sound.
与在高空飞行的飞机不同，直升机不容易被雷达发现，因为它的飞行高度较低，且常常被地形所隐藏，因此最大的问题是噪音。
Differences of echo characteristic between impulse radar and continuous wave radar are analyzed, and the potential of UWB impulse for Super-Low-Altitude target-detection is remarked.
