基于PXI总线的飞航导弹高度通道动态测试系统的设计与实现

Design and Realization of Dynamic Test System for Altitude Channel of Winged Missile Based on PXI

针对飞航导弹高度通道测试技术多以定高特征点性能检测为主,无法对整个工作过程进行全面考核的现状,从无线电高度表的测试技术出发,介绍了其测高工作原理,分析了现行测试方法的不足,提出了过程测试方法;通过对现有自动化检测系统进行功能扩展,研制了基于PXI总线的导弹高度通道动态测试系统,实现了无线电高度表的过程测试,并在导弹全弹道仿真中得到了应用,为飞航导弹其它控制环节的动态检测技术提供了参考与借鉴.

The conventional altitude channel test technology of winged missile chiefly depends on constant characteristic altitude inspection,which is restricted in the entire operation process examination.Based on radio altimeters test technology,the altimetric measurement principle is introduced,and the present testing principle and its insufficiencies of the altimeter are analyzed,then the dynamic testing method is proposed.By means of the functional expanding for the automatic testing equipment,the altitude channe...
