伪随机码体制具有较强的抗杂波干扰能力和良好的距离分辨率,是一种理想的无线电近炸引信体制。本文分析了以平均飞散速度运动的爆炸破片击中目标质心这样一种典型情况下对弹丸适时爆炸的要求,建立了计算最佳启爆延迟时间τ_0的数学模型,对伪随机码调相引信信息处理方法进行了较详细分析。介绍了利用单片机设计引信信息处理电路的基本方案,成功实现了把微电脑与存储技术用于近炸引信的设计,对实验结果也作了说明。
Pseudo-random code system has strong anti-clutter interference ability and good range resolution, is an ideal radio near-fuze system. In this paper, we analyze the requirement of a projectile exploding in time under the typical condition that an explosive fragment moves at an average flying speed and hit the target centroid. A mathematical model for calculating the optimal ignition delay τ_0 is established. The pseudo-random code phase modulation fuze information Processing methods were analyzed in more detail. Introduced the use of single chip design fuze information processing circuit of the basic program, the successful implementation of the microcomputer and memory technology for the design of near-fuze, the experimental results are also described.
