Research On Efficient Oppressive Jamming Technology Against The Interferometric Synthetic Aperture Radar

Interferometric synthetic aperture radar (InSAR) is a kind of radar system whousing two SAR complex images of the interference between the phase difference, thencan achieve the target height information, with large scope, all-weather and has certainadvantages of penetration. Because it is in the military, economic, and scientificresearch in areas such as widely used, makes the InSAR interference technique isbecoming more and more widely attention.The study is began with the basic principle of InSAR imaging, and launchedinterferometric synthetic aperture radar pressing type jamming. Firstly, it is analyzed theInSAR imaging principle, the InSAR height measurement model, and discussed thebasic process of InSAR data processing. Secondly, it is analyzed the possibility ofInSAR jamming, the SAR jamming equation, and deeply studied the mechanism ofsuppressing jamming by a single jammer, simulated the InSAR jamming effect of theradio frequency jamming and noise amplitude modulation jamming and noise frequencymodulation jamming. Finally, it is studied the effective suppressing jamming with thejamming equation, mainly analyzed and simulated the jamming mechanism and thejamming effect of the sinusoidal frequency modulation jamming and the sawtooth wavefrequency modulation jamming and the noise FM pre-emphasis jamming and thedistributed jamming.
