英文摘要：

The principle of DRFM multiple-false targets was expounded and the effect of DRFM quantization digit on harmonic amplitude was analyzed. Aiming at the missile-defense guidance radar, simulation research of jamming narrow and wide system was studied respectively. Then, the power requirement and receiver sensitivity for jammer were illuminated. Especially, the influence of quantization digit of DRFM on pulse compress and radar imaging was discussed detailedly. Lastly, several technical and tactical scenarios were put forward for improving jamming performance.
