| Abstract: | A design of a CW radar signal simulator based on Direct Digital Synthesizer and its operation principle are described, the operation principle and speeifications of the main parts are introduced. Practice has proved that it has more advantages, such as wide dynamic output range, high steady frequency, low power consumption, long working hours, convenient use and so on. At the end of this paper, the expression to calculate the RCS of signal simulator is provided. |
