Disorder System Signal Spectrum to Steal Velocity Range Gate

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