摘要
为了研究仿形诱饵体的毫米波辐射特性,在目标毫米波探测原理的基础上,建立了辐射计对地面目标的归一化天线温度对比度模型,分析了目标在不同状态下的归一化天线温度对比度;实验获得了诱饵材料和某型装甲目标的毫米波辐射信号,通过对信号的处理,提取目标信号的时域特征,对比分析了实验和计算的信号特征量。结果表明,仿形诱饵体和装甲目标有着相似的作战效能,诱饵材料的毫米波辐射特性的研究对仿形诱饵体的设计提供了一定的理论依据。
To research the millimeter wave radiation characteristics of profiling decoy target, based on target millimeter wave （MMW） de- tection principle, the normalized antenna temperature contrast model that radiometer scans ground target was established, and the normal- ized antenna temperature contrasts of the targets under different conditions were analyzed; Through experiments, millimeter wave radiation signals of decoy material and a certain type of armored target were obtained, and through the signal processing, the time - domain features of the target signals were extracted, and the signal characteristics of experiment and calculation were compared and analyzed. The results show that the profiling decoy target and the armored target have similar operational effectiveness, and the decoy material millimeter wave ra- diation characteristics research can provide certain theoretical basis for profiling decoy target design.
