多元双色红外导引头抗干扰技术研究

The Anti-Jamming Technique for Multi-Element Dual-Band IR Seeker

介绍了双色红外导引头的基本工作原理,分析了目标与诱饵干扰的红外光谱特性,对采用多元体制与多元双色体制进行抗干扰的方法进行了研究,着重介绍了干扰弹光谱检测技术、双色比波门抗干扰技术、时间波门抗干扰技术、干扰弹能量检测技术以及跟踪策略抗干扰技术;最后给出了导引头抗干扰试验的结果。

This paper introduces the operating principle of a multi-element dual-band IR seeker for air-to-air missile. For improving the seeker＇s anti-jamming ability, the paper analyzes the IR spectral characteristics of the targets and artificial IR disturbances, and then studies the spectra-detecting technique, the dual-band ratio technique, the time window technique, the energy-detecting technique and the tracking technique. Finally, the paper shows the anti-jamming test results of the seeker prototype.
