“…The current tracking radar countermeasures tend to use deception jamming because the active emission of a high-power noise jamming signal can be very easily traced and combated. The existing track deception jamming techniques implemented by DRFM have suffered from a low number and fidelity of false targets [5][6][7]. These methods require that the incident signal be intercepted, followed by the analysis and calculation of the corresponding jamming signal.…”

“…A limitation of the current study is that the actual effect has not been demonstrated experimentally at present; we aim to focus on this in future research. In addition, the false tracks generated by this method were limited to the distance dimension, and distanceazimuth two-dimensional deception has yet to be achieved [5][6][7]. In existing studies, PSS has shown more severe restrictions on the angle and frequency of the incident signal in practical experiments, which is one of the reasons why PSS material design is more popular.…”

“…It uses digital frequency memory (DRFM) to sample and store the received signal, followed by delayed forwarding according to certain rules. It eventually displays a false track on the opponent's radar display [5][6][7], tricking the radar into searching and tracking and wasting its limited resources. However, active devices are costly to design and require the interception of priori information, making practical work more complex.…”

Track processing is the foundation of radar multi-target tracking, and the processing performance for jamming has particular research significance when it comes to protecting high-value targets. At present, passive jamming using a modulated metasurface exhibits a fast response and a flexible operation mode. However, most research in this area has been carried out at the radar signal processing level and less at the data processing level. In this paper, a range of false target track deception method based on a phase-switched screen (PSS) is proposed, and the relationship between the matched filtering output, radar detection, and track processing is derived. This method uses PSS to generate multiple false targets with controlled spatial distribution and magnitude, which can form high-fidelity false tracking tracks. The number of false tracking tracks can be flexibly altered by controlling the modulation parameters. The simulation results validate the effectiveness of the proposed method.

“…[1,2] and gained substantial attention from researchers due to its flexible beam scanning characteristic [3][4][5][6][7][8][9]. By employing a tiny frequency offset across adjacent array elements, the FDA can provide a time-range-angle-dependent beampattern, which makes it possible to suppress the rangedependent clutter or main-lobe interference through a proper beamforming method [10][11][12][13].…”

The frequency diverse array (FDA) can provide degrees of freedom in both the range and angle domains by controlling the frequency offset across adjacent elements. Nevertheless, the time-variant problem affects the analysis and application of FDA, and there is a notable lack of research on the receivers of multicarrier FDA. In this paper, a novel perspective to understand the factor of time parameter is proposed. Furthermore, combined with the multiple input and multiple output scheme, two multicarrier FDA radar receivers are proposed to obtain the time-invariant and dot-shaped beampattern. Numerical simulations demonstrate the validity of theoretical results.This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.

“…Taking into account the effect of time delay, the FDA deceptive jamming model is rederived in [21]. The deceptive interference signal flow is corrected in [22,23], and a new range dimension deceptive interference method is proposed. Yang Chen [24] proposed a composite interference method of suppression and range deception for FDA-MIMO beamforming.…”

Frequency diverse array-multiple-input multiple-output (FDA-MIMO) radar makes it transmit beam range–angle two-dimensional freedom by attaching a small frequency offset increment between the array elements. With the widespread use of digital radio frequency memory (DRFM) technology, it is able to delay the false target to any range bin and doppler unit by delaying and forwarding the radar transmits signals, resulting in the deceptive jamming effect of range dimension. To this end, based on the research of the existing main-lobe deceptive interference methods, this paper proposes a new improved MUSIC method based on the FDA-MIMO radar against deceptive jamming in the range dimension. Firstly, the range information of target and jamming is determined through spatial spectrum search by using the mismatch of jamming in the airspace position and range bin position, and then the process of range dimension deceptive jamming suppression is given. The simulation analysis results show that the proposed anti-jamming method can effectively mitigate against range dimension deceptive jamming.
