地面积水与装甲目标毫米波被动探测信号差异研究

以往毫米波被动探测中以平面金属目标代替立体金属目标(如装甲目标),而平面金属目标的探测信号又和地面积水的探测信号非常相似,所以导致这三种目标难以分辨。针对这一问题,从毫米波被动探测平面金属、积水、装甲目标探测信号的基本理论出发,通过建立目标模型、推导天线温度计算模型,仿真得到了这三种目标的探测信号,查找信号差异并分析总结了造成差异的根源。仿真结果证实了分析的正确性和有效性,为地面装甲目标识别算法的研究提供了必要的理论支撑和分析依据。

Research on Signal Differences of Water and Armored Target with Passive Millimeter Wave Detection Technology

In the past, people always use planar metal instead of armored target in passive millimeter wave detection, and the detection signal of planar metal and water is very similar, so it is difficult to distinguish these three targets. To solve this problem, started from the basic theory of passive millimeter wave detection, established the target model, deduced the antenna temperature calculation model, simulated the detection signal and found the source of signal differences, summarized and analyzed the roots of the differences. The simulation results demonstrate the validity and feasibility of the conclusion, which provides necessary theoretical support and analytical basis for the study of armored target recognition algorithm.
