A New Three-Dimension Deceptive Scene Generation against Single-Pass Multibaseline InSAR Based on Multiple...

Area of Science:

• Electronic Warfare
• Radar Systems Engineering
• Signal Processing

Background:

• Interferometry synthetic aperture radar (InSAR) deceptive jamming using two transponders can create false 3D scenes in single-baseline systems.
• Multibaseline InSAR systems can reduce the effectiveness of simpler deceptive jamming methods.

Purpose of the Study:

• To propose a novel deceptive scene generation method for multibaseline InSAR systems.
• To enhance the deceptive capability of InSAR jamming against advanced multibaseline configurations.

Main Methods:

• A new method employs multiple transponders, each modulated with a complex coefficient.
• Complex modulation coefficients are calculated offline by solving a matrix based on desired false point coordinates.
• The method integrates complex coefficients with a deceptive scene template for rapid 2D SAR deceptive scene generation, enabling large 3D scene creation.

Main Results:

• The proposed method effectively generates deceptive 3D scenes in multibaseline InSAR images.
• Effectiveness is achieved when the number of transponders is not less than the number of antennas in the multibaseline InSAR system.
• Computer simulations validated the proposed method's effectiveness.

Conclusions:

• The novel multiple transponder-based method provides effective deception for multibaseline InSAR systems.
• This technique overcomes limitations of previous methods against multibaseline configurations.
• The approach allows for the rapid generation of complex 3D deceptive scenes.
