目标近区散射特性和辐射特性的研究是无线电引信的关健基础课題之一。如何克服目标闪烁效应,对提高引战配合效率具有重要意义。毫米波被动式引信有着十分良好的目标近区辐射特性,能克服目标的闪烁效应,并具有良好的隐蔽性和抗干扰性,为解决引战配合提供了一条较为理想的途径。文章主要讨论了对空目标的毫米波辐射温度模型,对空毫米波被动式引信的天线温度模型,为对空毫米波辐射特性研究提供了理论依据。最后通过实验,首次验证了对空毫米波被动式引信的可行性。
The study of the scattering and radiation characteristics of the target near-field is one of the key topics of the radio fuze. How to overcome the target scintillation effect is of great significance to improve the efficiency of the lead warfare cooperation. The millimeter-wave passive fuze has very good target near-field radiation characteristics, can overcome the target’s scintillation effect, has good concealment and anti-interference, and provides an ideal way to solve the lead-in war. This paper mainly discusses the temperature model of the millimeter-wave radiation to the empty target and the antenna temperature model of the passive millimeter-wave passive fuze, which provides a theoretical basis for the study of the radiation characteristics of the empty millimeter wave. Finally, through experiments, for the first time verified the feasibility of empty millimeter wave passive fuze.
