| 摘 要： | 设计一种新型线性调频信号源,该信号源有别于应用直接数字频率合成（DDS）产生线性调频信号的方法,并且可对信号的起止和幅度进行控制。该设计可通过dsPIC,对由MATLAB根据线性调频公式计算出数据点后嵌入FPGA中的ROM所产生的线性调频信号进行起止以及幅度的控制。仿真和实验结果表明,该设计具有易实现,信号参数可时变性高,信号幅度、相位可预失真等特点。

| Abstract: | A new linear frequency modulation signal source is designed which is different from that produced by direct digital frequency synthesizer(DDS),and the starting and ending time and amplitude of the signal could be controlled by this new linear frequency modulation signal source which are produced by inserting the calculated data points according to the linear frequency modulation formulation with MATLAB in the ROM of the FPGA through dsPIC.Simulation and experiments show that the design is easy to implement,... |
