基于某型火箭发射器的虚拟脉冲信号分析

Analysis of Virtual Pulse Signal on the Certain Rocket Launcher

某型航箭发射器火箭弹的发射依靠脉冲电流信号,航箭发射控制系统正是根据送来的脉冲电流信号,控制航箭发射器从而实现航箭按不同发射方案的选择。采用Lab VIEW虚拟仿真技术,设计产生符合要求的虚拟脉冲,并通过叠加高斯白噪声来表示真实世界的脉冲信号;叠加后的信号经巴特沃斯滤波器进行滤波后,可模拟真实脉冲电流信号。对该脉冲电流信号进行均方根幅值谱变换,并对该信号进行了分析,最后通过在某型航箭发射器模拟发射演练中,证明该信号可表征真实脉冲信号。

The emission of the rocket launcher depends on current pulse signal which is sent from the launcher control system to control different transmission scheme. Lab VIEW simulation technology is used to produce a virtual pulse,and then superposing the Gaussian white noise on the virtual pulse to represent the real world pulse signal. The superimposed signal can simulate the real pulse current signal by filtering of Butterworth wave filter. The RMS signal amplitude spectrum is transformed. Finally,it is proved by the analog transmission of a certain type of rocket launcher that the signal can be characterized by a true pulse signal.
