With the wide application of pulse modulated RF pulse technology, accurate measurement of pulse envelope signal requires many parameters to characterize. Therefore, this paper firstly analyzes the definition of the pulse envelope signal. Then, from a mathematical point of view, analyzes the calculation of the pulse amplitude based on the IEEE histogram method and the calculation of the top fitting line based on the least square method. Finally, the calculation of the measurement parameters of the pulse is applied to the peak power analyzer. The practical results show that the design can obtain the measurement parameters of the pulse envelope signal quickly and accurately, and can be widely used in digital communication, navigation, radar and other systems.
