“…Compared with the linear frequency modulated (LFM) waveforms [26], the frequency offset can control the position of the false point target or scenes and control the appearance and disappearance of the false point target or scenes. The study of FDA interference was first mentioned in the 2018 IGARSS conference paper [34] and expand further by [35]. We should note that this paper is the extension of [34].…”

Most of the existing deception jamming techniques focus on designing effective jamming signals for static targets or scenes. This paper proposes a multi-scene deception jamming against synthetic aperture radar (SAR) imaging with frequency diverse array (FDA) antenna. Different from traditional singleelement and phased-array antennas, FDA antenna employs a small frequency offset across the array elements to produce angle-, range-and even time-dependent transmit beampattern, which brings bright prospect for the application of new jamming techniques against SAR imaging. Such a new method will generate many false targets or multiple deception scenes for the jammed SAR, which helps jam better on the static scene and moving target. Moreover, the location and number of false targets can be manipulated. This paper will illustrate the FDA-based deception jamming against SAR imaging, specially designed waveform and the relationship between the number of false targets or scenes and FDA parameters. The relationship between the location of false targets and the position of jammer will also be described in detail. All proposed methods are validated by extensive simulation results.

“…It generates multiple false targets at various distances across the slant range but at the same azimuthal range which aligned with the actual target as shown in the simulation (Figure 2). A good effort [35] has been made in the field of deception jamming using FDA which generates multiple fake targets at different positions in the slant range and azimuthal range to confuse the opponent radar. Four elements array with adjacent distance of half wavelength were used in FDA with frequency offset 500 kHz, and its simulation of [35] is shown in Figure 3, which reflects actual target at slant range 7500 m and azimuthal range 0 m along with four false targets which are situated at slant ranges 3 Wireless Communications and Mobile Computing 7300 m, 7395 m, 7615 m, and 7750 m with azimuthal range at 100 m. Figure 4 shows the effectiveness of the technique [36] by considering the jammer at the middle of the scene (7500 m, 0 m); this algorithm generates four false targets at different locations.…”

“…The technique is unable to draw false targets at different azimuthal ranges other than azimuthal range of the actual target. A novel approach in the field of deceptive jamming has been introduced in [35] with wave scattering using FDA for space-borne synthetic aperture radar (SAR). This approach considers the scenario where we offer deceptive jamming to the opponent radar for securing our valuable targets in its own territory with the help of placing deceptive reflectors.…”

Deceptive jamming is a popular electronic countermeasure (ECM) technique that generates false targets to confuse opponent surveillance radars. This work presents a novel approach for hiding the actual target while producing multiple false targets at the same time against frequency diverse array (FDA) radar. For this purpose, the modified FDA radar is assumed to be mounted on the actual aircraft. It intercepts the opponent’s radar signals and transmits back to place nulls in the radiation pattern at the desired range and direction to exploit FDA radar’s range-dependent pattern nulling capability. The proposed deceptive jammer produces delayed versions of the intercepted signals to create false targets with multiple ranges to confuse the opponent’s radar system. The novel mathematical model is proposed whose effectiveness is verified through several simulation results for different numbers of ranges, directions, and antenna elements.

“…However, the existing many traditional SAR interfering techniques such as noisy barrage jamming, shift-frequency jamming, intermittent sampling repeater jamming and scattered-wave jamming are hardly used to jam InSAR [10][11][12][13][14]. That is because the phase of the imaging output from the jamming signals is a constant related to the transponder's position, causing the jamming signals easy to be eliminated [15][16][17].…”

The interferometry synthetic aperture radar (InSAR) deceptive jamming method utilizing two synergetic transponders can generate a false three-dimension (3D) scene in a single baseline InSAR image. However, such deceptive capability could be reduced by the multibaseline InSAR system. To obtain effective deception on multibaseline InSAR, a novel deceptive scene generation method jointly employing multiple transponders is proposed. It only demands that each transponder is modulated with a complex coefficient when generating a false point. The complex modulation coefficient can be offline calculated according to the deceptive point coordinate by solving a matrix. Besides, the complex modulation coefficient can be combined with the deceptive scene template, and thus a large 3D deceptive scene is able to be created quickly in the multibaseline InSAR image by using the fast two-dimension (2D) SAR deceptive scene generation algorithm. As long as the number of transponders is not less than the number of antennas of the multibaseline InSAR system, this proposed method is effective. The effectiveness of the proposed method is validated by computer simulations.
