THE INTERFEROMETRY PHASE OF INSAR COHERENT JAMMING WITH ARBITRARY WAVEFORM MODULATION

This paper focuses on the interferometry phase of an active coherent jamming in InSAR (Interferometry Synthetic Aperture Radar) images. Based on the signal models of coherent jammer, the jammingʹs imaging results are derived by employing the Omega-K algorithm. By comparing the imaging results of InSARʹs two channels, the jammingʹs interferometry phases for both working modes, the single-pass and repeat-pass modes, are proved to be constants. And the values of the interferometry phases are determined by the jammerʹs geometry position relative to InSAR baseline, but independent of the jammingʹs waveform modulation and its background terrain.
