【Abstract】 Aim To study the realization of data acquisition system in a monopulse guidance radar and how to design a proper test method and test parameters. Methods The system was decomposed and several schemes were compared. On the test of system performance, the influence of input signal’s frequency was studied. Results An optimized solution was promoted for the data acquisition system, and also a method was introduced in the test parameter design. Conclusion This data acquisition system has been proved stable and excellent in the whole radar system.更多还原
