摘　　要：飞机振动特性测量与分析,对于飞机识别和探测系统的设计与评估是至关重要的;在简要介绍了振动特性测量理论之后,针对外场环境条件,设计了飞机振动特性激光测量装置和测量方法,并经过实验室验证;在全尺寸飞机试验与测量过程中,获得了有效的原始测量数据,计算出飞机振动特征量:平均中心频率和二阶中心矩;同时指出了在飞机振动测量中应注意的问题;试验表明,飞机振动特性测量与分析方法正确、有效。The t and analysis of the characteristic of the vibration from aircraft is of crucial importance for the aircraft detection system design and evaluation. A brief introduction of the measuring theory of the laser vibration from the target is presented in this paper. By analyzing the measuring condition in outfield test, the laser systems and test steps are designed of measurement for aircraft vibration and verified by the experiment in laboratory. The original measuring data obtained are used for calculating the characteristic parameters of the vibration such as mean central frequency and second order central moment from full size aircraft in test. Some problems put forward should pay attention to in the test. The method of measure- ment and analysis is proved an effective and correct to get the characteristic of aircraft vibration by laser system in the outfield test.
