| Abstract: | Width pulse extracting plays a very important role in System of Electronic War(EW). The instantaneous frequency indicator is an important equipment of EW, and its traditional width pulse extracting methods have many shortcomings. A new width pulse extracting method is presented, which sets two thresholds, uses AC-DC coupling processing,and has strong signal adaptability and high accuracy of pulse width. The experiment shows that this design is feasible and effective. |
| Keywords: | Electronic war Width pulse Instantaneous frequency indicator Two thresholds |
