| Abstract: | Digital radio frequency memory (DRFM) is a key component of the coherent repeater to deceive modern radar system, which has been used to retransmit the replica of the radar waveform at the optimum time for maximum deception. The basic operation principle of the multiple-bit amplitude quantization DRFMs was discussed, and then the general technique of Simulink modelling & simulation for multiple-bit DRFMs was proposed. The effect of the quantization levels on the spur performance of the multiple-bit DRFMs was proposed. The corresponding Simulink model was given. The result of the simulation was analyzed in detail and the simple result of theory analysis was verified. |
