在20世纪60年代的越南战争中,无人值守地面传感器崭露头角。当时为了切断隐藏在热带丛林中的“胡志明小道”——越军通往南越的运输线,美国将刚刚研制出的“白尾”系统投入战场。美国飞机沿“胡志明小道”投放了称做“热带树”的声/地面震动传感器,以采集在此道上行进的车队和部队所产生的声音和地面震动,并传送给指挥中心。指挥中心根据获取的信号,可以确定车队/部队的位置、规模、行进方向等,指挥飞机实施轰炸。它在越南战场的成功使用,促
In the Vietnam War in the 1960s, unmanned ground sensors came to the fore. At that time, the United States put the newly developed “white tail” system on the battlefield in order to cut off the “Ho Chi Minh trail” hidden in the tropical jungle - the Vietnamese military transport line to South Vietnam. The U.S. aircraft launched an acoustic / ground-based vibration sensor called “Tropical Tree” along the “Ho Chi Minh Trail” to collect sounds and ground vibrations from the convoy and force traveling on this road and send it to the command center. Based on the signal obtained, the command center can determine the position, size and direction of the fleet / force and direct the aircraft to bomb. It successfully used in Vietnam battlefield, promote
