摘要
讨论了宽带信号的模型及条件 ,在此基础上对宽带线性调频信号在宽带模型下的距离、速度及速度距离联合分辨率特性进行了分析和模拟 ,并对宽带模型及窄带模型下的结论进行了比较 ,证明了信号分辨力取决于信号频谱结构及尺度 ,得出了两种模型下信号分辨力特性的关系。
By analyzing the model of wideband signal and the condition of narrow band signal model, the paper discusses the range and velocity resolution of the LFM signal used in the wide band radar and sonar. It proves that the resolution of the LFM signal is affected by the spectrum and the scale of the signal. The relation between resolutions under two models is also discussed.
