Abstract:

This thesis presents a method to calculate the power level of harmonics generated in DRFM due to sampling and quantization process. The Fourier series analysis is used for the calculation of the harmonic levels. Quantization process will generate the harmonics of the fundamental signal which will be folded into the DRFM instantaneous bandwidth by the sampling process. Power level of the harmonics is dependent on the number of quantization bits of analog-to-digital converter. Further it is also dependent on the ratio of signal frequency to sampling frequency. MATLAB programs for computation of harmonic power levels and plots of harmonic power levels of multibit DRFM are included in the thesis. Some applications of the DRFM like deception jammer, broadband frequency source and radar simulator are also discussed. DRFM, Digital radio frequency memory, Quantization, Sampling
