“…Zhou et al designed an in-pulse orthogonal linear frequency modulation (LFM) phase coded waveform. In view of ISRJ, the waveform was divided into different sub-signals, and its corresponding matched filter was used to reconnoiter, identify and counteract the jamming effectively, but the situation of asynchronous sampling between the jamming and the transmitted signal was not considered [10].…”

According to the orthogonality of each sub-carrier in the multi-carrier phase-coded (MCPC) signal, this paper focuses on anti-interrupted sampling repeater jamming (ISRJ) and creatively proposes a novel radar signal based on time-frequency random coded (TFRC) method, namely TFRC-MCPC signal. Based on the perspective of waveform design, the TFRC-MCPC signal adopts a chaotic sequence with good pseudo-random to code each chip in time-domain and each subcarrier in frequencydomain. The TFRC method increases the pseudo-randomness of radar waveform pulses and reduces the correlation between radar echo and ISRJ, thereby effectively suppressing the interference of false targets. The TFRC-MCPC method and common filter design methods do not conflict with each other and can be used in combination. The simulation experiment results show that under the typical parameters described in the paper, compared with the traditional MCPC signal and LFM signal, the signaljamming ratio (SJR) improvement factor of the TFRC-MCPC signal is optimized by 1-2 dB after pulse compression, which verifies its feasibility and effectiveness.

“…The major disadvantage of these methods is that it assumes that the jammer has accurate information about environmental factors and receiver actions. For example, adaptive zero adjustment technology will decay the power of jamming signals, error detection and correction technology can reduce the symbol error rate (SER) of the received information, and anti-jamming methods such as in-phase and quadrature (IQ) imbalance [9] or anti-chirp-jamming [10] can fade the jamming signal influence. Game theory is a dynamic process between the jammer and the transmitter-receiver pairs; it can build a Nash equilibrium between both sides [11], but the jammer needs to employ an efficient jamming strategy, which is also the purpose of this paper.…”

Reinforcement learning (RL) has the advantage of interaction with an environment over time, which is helpful in cognitive jamming research, especially in an electronic warfare-type scenario, in which the communication parameters and jamming effect are unknown to a jammer. In this paper, an algorithm for a jamming strategy using orthogonal matching pursuit (OMP) and multi-armed bandit (MAB) is proposed. We construct a dictionary in which each atom represents a symbol error rate (SER) curve and can be obtained with known noise distribution and deterministic parameters. By reconnoitering, the jammer counts acknowledge/not acknowledge (ACK/NACK) frames to calculate the SER, which is also regarded as samples that are sampled from the real SER curve using an MAB. When we obtain the sampled sequence and the constructed dictionary, the OMP algorithm is used to search and locate atoms and its corresponding coefficients. With the searching results, the jammer can construct an SER curve that is similar to the real SER curve. The experimental results demonstrate that the proposed algorithm can learn an optimal jamming strategy with three interactions, which converges substantially faster than the state of the art.

“…The jamming technique against SAR‐GMTI can always be divided into barrage jamming and deceptive jamming. Barrage jamming can reduce the detection rate of moving targets via concealing the real targets in barrage plaques or strips [4–7]. On the other hand, deceptive jamming makes it difficult to distinguish fact from fable by generating deceptive moving targets which have the similar characteristics of scattering and motion with real ones.…”
