Noise jamming to ISAR based on multiplication modulation

Based on multiplication modulate method, this paper analyses the noise jamming to ISAR. The noise jamming signal of traditional method has no correlation with ISAR radar signal, and is easily dismissed. So, in this paper the imaging principle of inverse synthetic aperture radar is analyzed, the noise jamming method based on multiplication modulates against ISAR are discussed, and the correlation between jamming signal and radar signal is presented. Simulation proves the correctness of the presented analysis and proposed noise jamming method. (5 pages)
