In this paper, we develop an expression for the frequency spectrum of a digital radio frequency memory (DRFM) linear range gate stealer (RGS) electronic attack (EA) signal. A DRFM linear RGS EA signal has a slightly different center frequency than the input radar signal and evenly spaced harmonics or spectral lines. Previously, we presented a top-level analysis to predict the center frequency shift and the spacing of the spectral lines. However, our top-level analysis did not address the magnitude of the spectral lines. The expression developed in this paper reveals the magnitude of the spectral lines along with the center frequency shift and the spacing of the spectral lines. We also present laboratory spectral measurements to demonstrate the validity of the expression.
