摘　　要：文中提出了一种利用MATLAB产生模拟通信信号的基带I／Q调制数据，通过FPGA＋DAC数字正交上变频来实现中频模拟通信信号产生的设计方法。该方法实现电路简单，不需要专门的模拟器件。通过该方法来实现模拟通信信号的产生，为构建更加复杂的电磁环境，实现雷达电子战和通信电子战领域的交织融合提供了有力保障，具有很强的实用价值。A method of using Matlab to generate a baseband communication signal analog I/Q modulation data and the design meth- od to achieve analog communication signals generated by the FPGA＋DAC digital squadrature upconverter is preposed in this paper, this method has the advantages of simple circuit , without a specialized analog device. Through this method, the generation of ana- log communication signals can be realized, which has strong practical value for constructing more complicated electromagnetic envi- ronment and realizing intertwined fusion in the fields of Radar electronic warfare and communication electronic warfare.
