A Wideband Signal Generation System for radar and Electronic Warfare is presented. This system uses two DACs each can work at 1Gsps with 14-bit resolution and generate 500MHz bandwidth signal. The DDWS (Direct digital wave synthesis) method is used for signal generation and the data transfer and controlling is based on FPGA. The data for signal generation is stored in ZBT-SRAM and the system can communicate with the controller module through PC104+ interface. The system structure, implementation and test results are described in detail.
