本文研究了伪随机码相关技术用于无线电近炸引信可以大大地抑制地面、海面杂波以及人工和自然干扰,它对提高引信的抗干扰能力将是一个飞跃,我们作了初步试验,在构通系统的基础上,重点研究了引信用的编码技术。在编码技术的研究中,通过对频谱、相关函数和模糊函数的分析,认为这种体制的引信适合于低空、海面和地面目标。因为它具有尖锐的自相关特性和良好的距离分辨能力(决定于码元宽度)。在目前电子对抗战日益严重的形势下,它是一种理想的近炸引信体制,本文对此种引信体制的框图、原理、数学分析以及实际应用中的重要技术问题进行了研究。通过实验及对其实验数据和曲线分析,证实了此种体制引信具有上述优越性。
This paper studies the pseudo-random code technology for radio near-fuze can greatly suppress the ground, sea clutter and artificial and natural interference, it is to improve the anti-jamming ability of the fuse will be a leap forward, we made a preliminary test, in the structure Based on the system, we focus on the coding technology of fuze. In the research of coding technology, the fuze of this system is considered to be suitable for low altitude, sea surface and ground targets through the analysis of spectrum, correlation function and ambiguity function. Because of its sharp autocorrelation and good distance resolution (depending on the symbol width). In the current situation of increasingly serious electronic warfare, it is an ideal near-fuze system. This paper studies the block diagram, principle, mathematical analysis and important technical problems in practical application. Through the experiment and analysis of its experimental data and curves, this system fuze has been proved to have the above advantages.
