“…Combined with the measurement likelihood, an effective gating strategy based on the auxiliary information is introduced in this section to determine the attributes of the measurements in the presence of MRFT jamming in the dense clutter environment. Different from the existing antifalse-target jamming algorithms [1,2,10,11], the proposed method does not distinguish the true target measurements from the false target measurements directly. The method firstly divides the obtained measurements into two categories by source: the generalized newborn targets and the existing targets.…”

Multi-range-false-target (MRFT) jamming is particularly challenging for tracking radar due to the dense clutter and the repeated multiple false targets. The conventional association-based multi-target tracking (MTT) methods suffer from high computational complexity and limited usage in the presence of MRFT jamming. In order to solve the above problems, an efficient and adaptable probability hypothesis density (PHD) filter is proposed. Based on the gating strategy, the obtained measurements are firstly classified into the generalized newborn target and the existing target measurements. The two categories of measurements are independently used in the decomposed form of the PHD filter. Meanwhile, an amplitude feature is used to suppress the dense clutter. In addition, an MRFT jamming suppression algorithm is introduced to the filter. Target amplitude information and phase quantization information are jointly used to deal with MRFT jamming and the clutter by modifying the particle weights of the generalized newborn targets. Simulations demonstrate the proposed algorithm can obtain superior correct discrimination rate of MRFT, and high-accuracy tracking performance with high computational efficiency in the presence of MRFT jamming in the dense clutter.

“…From Eqs. (14) and (15), it is obvious that the calculated IF of mixed target echo and jamming returns are all stationary and linear. It means that the conventional liner time-frequency analysis (TFA) methods are qualified to analyze their TF characteristics, such as STFT [20] and wavelet transform (WT) [21].…”

“…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.…”

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.

“…But from the maximum SINR criterion, the ADBF has reached the upper limit of performance. The polarisation filteringbased approach [15,16] can suppress the jamming in the same polarisation direction, while it cannot suppress all the jamming when there are more than two polarisation directions. And the hardware cost of the antenna doubles as the number of polarisation channels increases.…”

Traditional space-time adaptive processing (STAP) suffers from severe performance degradation in dense false target jamming scenarios, especially mainlobe deceptive jamming. To solve this problem, the superimposed stepped frequency (SSF) radar is explored and its ability in suppressing the mainlobe deceptive jamming is studied in this work. SSF radar can provide a controllable degree of freedom in range domain besides the traditional freedom in angle and Doppler domains, which can be used to distinguish true and false targets. Thus, the range cascaded STAP approach is proposed to suppress the deceptive jamming and the clutter. First, the true target and clutter are blocked in carrier frequency domain. Then, the jamming is attenuated by the adaptive filter in carrier frequency domain with the jamming covariance matrix being constructed by the blocked data. At last, the clutter can be suppressed by the cascaded STAP in the space-time domain. Simulation results demonstrate the effectiveness of the proposed radar framework and the processing approach in suppressing the clutter and jamming.This is an open access article under the terms of the Creative Commons Attribution-NonCommercial-NoDerivs License, which permits use and distribution in any medium, provided the original work is properly cited, the use is non-commercial and no modifications or adaptations are made.
