针对地面隐身装甲目标的探测问题,采用有、无隐身材料的金属板,分别模拟战场上隐身、非隐身装甲目标,并通过控制它们自身的物理温度来模拟装甲目标发动机的不同工作状态。利用研制的毫米波辐射计进行探测,获取了地面背景下的金属目标和涂层隐身金属目标由“冷目标”—“隐身目标”—“热目标”变化过程的特征信号,验证了无源探测对涂层隐身金属目标的探测原理。本实验对反涂层隐身金属目标探测原理进行了有效、直观的演示,为反隐身目标探测提供了思路和依据的同时,也在培养学生工程实践能力和创新能力中取得良好效果。
In order to detect hidden stealth armor targets on the ground, metal plates with and without stealth material were used to simulate stealthy and non-stealthy armor targets on the battlefield respectively and to simulate the different operating states of armored target engines by controlling their own physical temperatures. Using the developed millimeter wave radiometer to detect, the metal target and the coating stealth metal target in the ground background are acquired by the characteristic signals of the change process of “cold target ” - “stealth target ” - “hot target ” , Verified the detection principle of passive detection on the coating stealth metal target. In this experiment, an effective and direct demonstration of anti-coating stealth metal target detection principle is provided, which provides ideas and basis for anti-stealth target detection, and at the same time, it also achieves good results in training student engineering practice ability and innovation ability.
