摘要
针对传统伪码调相脉冲引信信号源产生设计复杂、成本高昂的问题,利用PXI-5641R板卡设计了一种更高效快捷的伪码调相脉冲引信信号产生系统。在分析了伪码调相脉冲引信工作原理和相关波形形式的基础上,利用LabVIWE图形化语言环境和PXI自带工具包完成软件设计。主控制计算机产生伪码调相脉冲信号,由FIFO传输到PXI-5641R板卡,经过中频调制输出。通过示波器的观测分析,输出信号稳定,具有较强可扩展性,适合在模拟实验或调试阶段适用,对研究伪码调相脉冲引信有一定指导作用。
Fuze is the missile terminal damage control system, playing an important role in modern warfare. Aiming at the problem of complex design and high cost,the PXI-5641R board is used to design a more efficient PN code phase modulated pulse signal generation system. Based on the analysis of the working principle and related waveforms of PN code phase modulation fuze, the software is designed by using LabVIWE graphical language environment and PXI toolkit. The main control computer generates PN code phase modulation pulse signal, transmitted by the FIFO to the PXI-5641R board, after the intermediate frequency modulation output. Through the observation and analysis of the oscilloscope,the signal output is stable and strong scalability, suitable for simulation experiment or debugging stage, to study the PN code phase modulation pulse has a certain guiding role.
