Abstract :

In the current paper, linear Digital Radio Frequency Memory (DRFM) is tested to steal Velocity Range Gate for use inelectronic war. DRFM output signal steal both of the interval and velocity gate. This output signal spectrum has twoimportant characteristics that, we use them in this paper. First, the central frequency shift is smaller and measurablethan the central frequency of input signal. Second, the presence of harmonics with small amplitude being around thecentral frequency of the data shift. The main factor of the spectrum characteristics is the discrete nature of DRFM. Weinvestigated the development of the states to predict the central frequency shift and harmonics location as a function ofradar and DRFM parameters. When electronic war engineers could affect the system performance, these spectrumcharacteristics are taken attention. The analyzers of signal by these spectrum characteristics can evaluate electronicwar systems better.
