Rf Pulse Spectrum Estimation

This paper is concentrated on data processing,mainly including high resolution spectrum estimation,and system software developing which applied in a kind of phase noise measurement system of pulse modulation wave.In the paper, the expression method of the frequency stability of the pulse modulation wave was expounded. The paper points: frequency stability of the pulse modulation wave well used the power spectrum density function to indicate, not Allan variance. A new middle frequency spectrum analysis frequency stability measurement method on band pass sample technique was put forwarded. The system design formula on the new method were found. A pulse modulation wave frequency stability measurement laboratorial system was developed.The system software of the device has been completed whith modular programming and OOP using Delphi 7.0 . Theory analysis and experiment results show: The new method has broad applying prospects. The system software can be operated easily and work at high reliability.
