| Abstract: | Introduces a high reliability design of the radar signal generator based on direct digital frequency synthesizer. Achieve asingle frequency, linear FM and step frequency radar signal output with the highest frequency up to 400 MHz. A close-loop circuitthat monitors the state of the system is added to improve the reliability of the system. The test result indicated that the system output has a stable frequency and a high reliability. |
