目标与背景的对比度分析及其应用

Analysis and application of the contrast of object and background

较深入地分析了目标与背景的对比度及其时间、空间和光谱特性,介绍了基于目标与背景的对比度的红外对抗和反对抗措施,如变频技术、变向技术、假目标等红外对抗措施以及太赫兹波探测、时间鉴别法和光谱鉴别法等红外反对抗措施。

The contrast of the object and the background with its time behaviors,spatial and spectral characteristics is analyzed. Some infrared countermeasures and counter-countermeasures based on the contrast of the object and the background are introduced. The technique of frequency and direction conversion, the false target as the infrared countermeasures and THz wave detection,the technique of time and spectral discrimination as the infrared counter-countermeasures are listed as the examples.
