红外成像导引头抗干扰性能评价指标体系

目前,各类红外成像制导导弹面临的主要问题是抗干扰能力的强弱,包括自然环境干扰和人工干扰两种;因此红外导引头的抗干扰性能成为各类红外制导导弹的关键性能,极大地影响到导弹的作战性能;为了能够合理的评价红外成像导引头的抗干扰性能,就必须制定合理的红外成像导引头抗干扰性能评价指标;为此,笔者根据红外成像导引头的抗干扰工作过程及其特点,以及传统的评价指标,并借鉴深度学习的评价指标,提出了由截获能力、识别能力、跟踪能力和命中精度能力这四方面组成的抗干扰性能评价指标体系;明确了四项指标下的二级指标内涵和计算方法,根据红外仿真与数据处理结果表明,这4种评价指标均可以有效地体现出导引头抗干扰性能的强弱,而且识别能力和命中精度这两个指标更加突出,故笔者所提出的红外成像导引头抗干扰性能指标体系及其计算方法,均可成为红外成像制导导弹抗干扰性能评估的判断依据.

Infrared imaging guide head anti-interference performance evaluation index system

At present, the main problem facing various types of infrared imaging guided missiles is the strength of anti-jamming capabilities, including natural environmental interference and artificial interference. Therefore, the anti-jamming performance of the infrared seeker has become the key performance of various infrared guided missiles, which greatly affects the combat performance of the missile. In order to reasonably evaluate the anti-jamming performance of the infrared imaging seeker, it is necessary to formulate a reasonable evaluation index for the anti-jamming performance of the infrared imaging seeker; for this reason, the author based on the anti-jamming work process and characteristics of the infrared imaging seeker, As well as traditional evaluation indicators, and drawing on the evaluation indicators of deep learning, an anti-jamming performance evaluation index system composed of four aspects: interception ability, recognition ability, tracking ability and hit accuracy ability is proposed; the second level under the four indicators is clarified Index connotation and calculation method. According to the results of infrared simulation and data processing, these four evaluation indexes can effectively reflect the anti-jamming performance of the seeker, and the two indexes of recognition ability and hit accuracy are more prominent. The anti-jamming performance index system and calculation method of the infrared imaging seeker proposed by the author can be used as the basis for evaluating the anti-jamming performance of infrared imaging guided missiles.
