| Abstract: | In the rocket sled velocity measurement by cutting off wire,the reason of electronic measurement instrument reliability reduced in some strong electromagnetic interference is probed.Aimed at a particular strong electromagnetic interference environment,the signal is isolated and designed with the overall shape,and the time is tested by CPLD.The developed anti-electromagnetic interference Electronic Time Measurement Instrument has a good application effect.The design method and application is discussed in detail in this paper. |
