摘　　要：介绍了用毫米波多普勒雷达测量导弹电磁弹射系统模拟负载膛内速度的基本原理和方法,根据电磁弹射系统的特点设计测量方案。针对速度测量面临的两大关键技术,采取措施提高信号的信噪比,采用小波分析法去除多普勒信号的噪声和趋势项信号,利用极值法和短时傅里叶变换完成信号的多普勒信息提取,可获得连续完整的模拟负载膛内速度曲线,取得了较好的测量效果,可为导弹电磁弹射技术的研究提供数据支撑。The paper introduces the basic principle and interior trajectory speed measurement method of the artificial load by using the millimeter wave Doppler radar,designs the speed measurement way based the characters of the electromagnetic ejection.In allusion to the key techniques of speed measurement,we take action to improve the Signal-to-Noise Ratio(SNR),employ the wavelet analysis technology to eliminate the useless signal and the trend of the Doppler signal,utilize the extremum method and the Short-Time Fourier transform(STFT)to obtain the continuous speed curve,and good results are obtained.It provides the data support for the research of missile electromagnetic ejection launching technology.
