地面战场无人传感器是一种能对地面运动目标或低空飞行目标进行探测的技术侦察器材。其主要作用是利用设置在地面上的各种传感器,侦察地面运动目标或低空飞行目标的位置、性质、出现时间、运动速度、方向及行动规模等情报信息。地面传感器的工作过程是:运动目标所产生的地面振动波,声响、红外辐射、电磁或磁能等被测量,由探测器接收并转换成电信号,再由信号处理电路放大处理送入发射机进行调制后发射出去,由设在远处的接收机接收、解调和识别发现的目标。无人值守传感器大量应用于军事行动,给敌方的战斗行动带来了很大的麻烦。
Unmanned ground battlefield sensor is a ground moving targets or low-flying targets to detect the technology reconnaissance equipment. Its main function is to use various sensors installed on the ground to detect intelligence information such as the position, nature, time of occurrence, speed of movement, direction and scale of operation of ground moving targets or low-flying targets. The working process of the ground sensor is that the ground vibration wave, sound, infrared radiation, electromagnetic or magnetic energy generated by the moving target is measured and received by the detector and converted into an electrical signal, which is amplified by a signal processing circuit and sent to a transmitter for processing After modulation, it is transmitted and received by distant receivers to demodulate and identify the detected targets. The large number of unmanned sensors used in military operations have brought great troubles to the enemy's fighting operations.
