The Target Recognition Technology for Multi-Element Dual-Band IR Seeker

结合多元红外双色探测系统,对双色目标识别技术进行研究:采用辐射源位置信息确定中短波同源脉冲,并计算双色比,根据目标特性和干扰特性设置双色比门限,利用同源脉冲确定结果和双色比门限进行目标识别。实验结果表明,采用双色目标识别技术提高了目标识别的准确性,提高了导引头的抗干扰能力。

Improving the anti-jamming ability of infrared seeker, the Multi Sensor IR dual-band target recognition technology is researched： Firstly, the homologous pulses of infrared waveband are obtained by using the position information of the infrared radiation source, and then the radiation ratio of dual bands has been computed, and setting the threshold of the radiation of dual bands based on the characteristic of the target and the infrared flare. Finally, the target is recognized by the result of the homologous pulses and threshold of the radiation ration of dual bands. The results of experiments show that the target recognition technology based on the dual-band data fusion improves the accuracy of the target recognition and the anti-jamming ability of the IR seeker.
