“…With the idea of scatter-wave jamming, [14] deals with the jamming effect of sub-Nyquist jamming against ISAR where compressive sensing (CS) algorithm is applied to recover the image.

Airborne target's micro-motion such as rotation or vibration causes phase modulation, termed as micro-Doppler effect, into radar signals. The feature of micromotion is one of the most obvious features for radar recognition in mid-course phase. In traditional works, it is assumed that the micro-motion of the scatterer is the same as the ballistic target. However, with the variation of the aspect angle of ISAR, the position of the scatterer changes. In this paper, the movement of a ballistic missile in mid-course is modeled and analyzed. A false target jamming method is proposed by combining the micro-motion modulation and the electromagnetic scattering modulation. Compared with the methods using ideal point models, our method is able to generate a vivid false target with structural information, micro-motion and variation of the scatterer's RCS. The micro-motion effect of the false target is presented through ISAR imaging and time-frequency analysis. The effectiveness and correctness of the algorithm is verified by simulation.

“…In order to protect the important goals and regions of detection and observation, a variety of jamming techniques are designed against the ISAR system. Sub-Nyquist sampling jamming against the ISAR system is studied in [1][2][3][4]. In [1], sub-Nyquist jamming is used to the bistatic ISAR; by undersampling the intercepted signal of ISAR, multiple deceptive false targets will be induced and the real targets will be emerged in false targets.…”

Frequency diverse array (FDA) has attracted much attention in recent years due to its range-angle-dependent beampattern. Multiple-input multiple-output (MIMO) radar can offer waveform diversity to increase the virtual aperture length for azimuth coherent focus processing in radar imaging. Combining the advantages of FDA and MIMO radar, FDA-MIMO radar can steer multiple beams to different targets in the same line of sight (LOS) of radar with different waveforms. In this paper, an improved FDA model with the logistic map is proposed to get the aperiodic and range-angle uncoupling beampattern. Based on the proposed FDA, combining the FDA-MIMO radar, the waveform and chirp rate jitter techniques are adopted to mainlobe jamming suppression. Simulation results show the effectiveness of the proposed method.

“…Considerable attention has been paid to the electromagnetic jamming and anti-jamming for radar system in the electronic countermeasure (ECM) community over the past two decades [1][2][3][4][5]. To prevent or complicate the radar target detection and recognition, much work has been done on the jamming techniques, especially some new jamming tricks that appear to counter the wideband radar system, such as the interrupted sampling repeater jamming (ISRJ) [1][2][3][4][5][6][7][8][9], false-target digital image synthesizer (DIS) [10][11][12], and scatter wave jamming (SWJ) [13][14][15]. As a coherent repeater jamming, ISRJ firstly proposed by Wang et al [1] can induce a train of false targets after the pulse compression (PC) without completely sampling and storing the whole radar pulse.…”

“…Feng et al [4] explored the three conditions that should be met for the cancelation of target echo, including the repeater power, delayed time, and repeater frequency. Moreover, since the false targets induced by ISRJ always contain the phase variation information for cross-range resolution, the jamming trick also has been employed to generate two-dimensional false image and has showed its potential against radar imaging [5][6][7][8][9]. Wang and Cai [5] proposed the intermittent sampling jamming to counter the bi-and multistatic synthetic aperture radars (SARs).…”

Interrupted sampling repeater jamming (ISRJ) is an effective coherent jamming, which can induce false high-resolution range profile (HRRP) and image to greatly complicate the target detection and recognition of wideband radar. To counter ISRJ, an efficient filter is designed based on the time-frequency (TF) characteristic differences between target echo and ISRJ. Meanwhile, a feasible jamming suppression scheme is proposed, which not only could eliminate ISRJ but also could reserve the target echo. The main emphasis is that the received echo suppressed by our scheme is similar with the true target's HRRP on the basis of high correlation coefficient (CC) and large signal-jamming-to-noise ratio (SJNR) improvement factor. Simulation results are covered to illustrate the feasibility and validness of jamming suppression.
