摘　　要：针对传统的以模拟电路搭建的硬件引信信号预处理系统,具有受环境变化限制大,且在不同去噪条件下需要更换合适参数的电路元件才能适应不同信号降噪的要求等问题。本文提出基于实验室虚拟仪器(LabVIEW)软件平台下的逐点降噪方法,该方法可以实现实时显示系统对信号进行降噪处理的能力,并且可以根据不同环境、不同目标快速调节系统参数。经仿真测试表明,该系统在满足无线电引信预处理的条件下,具有响应速度快,信号参数可调,且在环境变化时对系统影响小等优点。The traditional hardware fuze signal preprocessing system is based on analog circuit.It is limited by the change of environment,and needs to uses the right parameters of elements to adapt the changing signal noises.In this paper,a new method of pointwise analysis filter based on LabVIEW platform is proposed.This method not only can display reduced noise in real time of the system,but also adjust the system parameters according to the different environments and targets quickly.The simulation results indicate that the method has the advantages of fast response,adjustable signal parameters and little influence on the system when the environment changes.
