摘要：

针对隐身飞行目标多谱带探测中所选波带性能不易准确客观进行分析评价这一问题，通过设计一种单元能量光谱探测系统来对所选探测波段进行客观分析，以证明该波段在红外隐身飞行目标多谱带探测的有效性．由于所选窄波段接收到的能量要小于传统所用的宽波段，而且信号本身无法表征对目标探测性能的优劣，故而通过对单元能量光谱探测原理进行分析，结合系统信号的转换模型，建立了波段质量因子这一评价模型在不同能见度、不同云背景以及不同探测距离情况下分别对所选窄波段性能加以客观分析．结果表明，单元能量探测系统在不同条件下不仅能够客观准确地对各波段探测进行分析，而且对于不同云背景下所使用波段的抖动性也给予了清晰直观的显示，证明了窄波段的探测效果优于宽波段，与理论分析相一致．

Abstract:

The performance of the selected bands in stealth aircraft target multi-spectral detection is hard to analyze and evaluate. A unit energy spectrum detection system is designed to analyze the selected detection band, demonstrating the availability of the selected detection bands. The selected narrow band receives less energy than the traditional wide band, while the signal itself can not represent the performance of target detection. By analyzing the unit energy spectrum detection principle and considering the alternative model of the system signal, the model of the wave quality factor is established to objectively analyze the performance of the selected band in different visibilities, cloud backgrounds and detection ranges. The result shows that the unit energy detection system can analyze each band detection objectively and accurately. At the same time, it also gives a clear and intuitive display of the jitter property while using it in different cloud backgrounds, proving that the detection effect of the narrow band is superior to the wide band and consistent with the theoretical study.

Key words: multi-spectral band, wave quality factor, spectrum detection, stealth target
