摘要
采用基于Chirp-Z变换的低阶频域等效系统方法对加入了不同比例的白噪声的飞机响应进行拟配计算,将得到结果与无噪声的响应拟配结果进行对比,分析得出这种拟配方法的抗噪声特性,以及白噪声对此方法的影响程度。
Low-order frequency domain equivalent system based on the Chirp-Z transform method was adopted to matching calculate the aircraft response that joined the different proportions of white noise, the results were compared with matching result without noise, the noise resistance characteristic and the influence of white noise based on this method were analyzed.
