摘要: 激光近炸引信工作于近红外波段，因其具有抗电磁干扰能力强，测距精度高以及方向性好等优点作为一种重要引信体制而被广泛应用。通过分析红外光场的变化来获取目标的散射特性，对于提高激光近炸引信的性能有着重要作用，基于此提出一种双频红外激光近炸引信方案，计算了红外光场与不同尺寸颗粒目标的散射特性，并分析了影响单个粒子散射相位函数的物理因素。研究结果表明，当粒子尺度小于激光波长时，散射光主要以后向散射为主；而当粒子尺度大于激光波长时，散射光主要以前向散射为主，进而探索出了一种可用于激光近炸引信的目标识别方法，证明了该方法的可行性和实用性。

Abstract: Laser fuze works in the near-infrared band. Due to its advantages of strong ability of resisting electromagnetic interference, high ranging accuracy and good directivity, near-infrared laser fuze has been widely used as an important type of fuze system. Obtaining the scattering characteristics of the target by analyzing the changes of the infrared light field plays an important role in improving the performance of the infrared fuze. Based on this, a novel dual frequency infrared laser fuze system was proposed. The theoretical calculation of the scattering properties of the infrared light field with different targets and analysis of the physical factors that affect the scattering phase function were carried out. The results show that when the particle size is smaller than the infrared laser wavelength, the scattered light is mainly backscattered. When the particle size is larger than the infrared laser wavelength, the main scattering light is mainly forward scattering. Therefore, a new identification method for different targets was proposed and proved the feasibility and practicability of this method.
