Special Issue Information

Dear Colleagues,

Waveforms are the means by which radars perceive the external environment and have always been a hot topic in the field of radar research. In recent years, radar waveform technology has been vigorously developed due to the diversity of targets, the diversification of radar tasks, and the complexity of the environment. At the same time, in order to effectively resist complex radar waveforms, electronic countermeasure technology has also been continuously developed. This Special Issue mainly focuses on the theme of radar waveform and countermeasures, summarizes the latest achievements in recent years, and aims to provide references for researchers.

Topics of interest include, but are not limited to:

  • Radar anti-interference waveform design technology;
  • Radar low-intercept waveform design technology;
  • Multi-function waveform design technology;
  • Radar beam anti-interference technology;
  • Interference waveform design technology;
  • Radar and interference dynamic countermeasure technology;
  • Electronic reconnaissance technology.

In existing phased-array radar systems, anti-jamming strategies are mainly generated through manual judgment. However, manually designing or selecting anti-jamming decisions is often difficult and unreliable in complex jamming environments. Therefore, reinforcement learning is applied to anti-jamming decision-making to solve the above problems. However, the existing anti-jamming decision-making models based on reinforcement learning often suffer from problems such as low convergence speeds and low decision-making accuracy. In this paper, a multi-aspect improved deep Q-network (MAI-DQN) is proposed to improve the exploration policy, the network structure, and the training methods of the deep Q-network. In order to solve the problem of the ϵ-greedy strategy being highly dependent on hyperparameter settings, and the Q-value being overly influenced by the action in other deep Q-networks, this paper proposes a structure that combines a noisy network, a dueling network, and a double deep Q-network, which incorporates an adaptive exploration policy into the neural network and increases the influence of the state itself on the Q-value. These enhancements enable a highly adaptive exploration strategy and a high-performance network architecture, thereby improving the decision-making accuracy of the model. In order to calculate the target value more accurately during the training process and improve the stability of the parameter update, this paper proposes a training method that combines n-step learning, target soft update, variable learning rate, and gradient clipping. Moreover, a novel variable double-depth priority experience replay (VDDPER) method that more accurately simulates the storage and update mechanism of human memory is used in the MAI-DQN. The VDDPER improves the decision-making accuracy by dynamically adjusting the sample size based on different values of experience during training, enhancing exploration during the early stages of training, and placing greater emphasis on high-value experiences in the later stages. Enhancements to the training method improve the model’s convergence speed. Moreover, a reward function combining signal-level and data-level benefits is proposed to adapt to complex jamming environments, which ensures a high reward convergence speed with fewer computational resources. The findings of a simulation experiment show that the proposed phased-array radar anti-jamming decision-making method based on MAI-DQN can achieve a high convergence speed and high decision-making accuracy in environments where deceptive jamming and suppressive jamming coexist.
