摘　　要：本文采用LM S公司的便携式模态测试系统,对某雷达产品的天线座结构系统进行试验模态分析,得出了该结构系统的前六阶固有频率及模态振型,并据此给出了具有实际意义的结论。同时,对如何将该技术在雷达结构中进行广泛应用,进行了一些有意义的探讨。Experimental modal analysis to a radar antenna pedestal structure by using of a modal test system developed by the LMS Company is conducted, natural frequency and modal vibration type of the structure in first six stages are obtained, and practical conclusion is given. Meanwhile widely application of this technology in radar structure is discussed.
