In this paper, we proposed two waveform design methods based on game theory to address the problem of radar detection performance degradation in electronic warfare. Since radar and jammer are completely hostile, their interaction is modeled as two-person zero-sum game. Signal-to-Interference-plus-Noise Ratio (SINR) criterion is used in formulating the utility functions. The existence of Nash equilibrium in games is verified by mathematical derivation. Different game waveform strategies are designed for different information levels of radar and jammer. Iterative water-filling method and two-step waterfilling method are designed to achieve Cournot equilibrium and Stackelberg equilibrium, respectively. Simulation results reveal that game strategies can bring higher radar detection performance than No game signal, especially when jammer power is lower than radar power. Radar detection probability based on game theory can be increased by up to 10% without changing the power. This demonstrates game strategies have great potentials for radar waveform design in electronic warfare.

“…However, the energy of the transmitted signal is reduced due to the amplitude weighting. An S-shaped range-angle beampattern has been achieved in [15] by combining nonlinear frequency modulation and logarithmic frequency offsets. A convex-multi-log-FDA system has been proposed in [16] in order to generate dot-shaped range-angle beampatterns.…”

In this paper, a multi-carrier nonlinear frequency modulation system based on pseudorandom frequency offset is designed. The reduction of the main lobe 3 dB width and the side-lobe peaks cannot be realized simultaneously in conventional beamforming schemes, especially when the number of array elements remains unchanged. The proposed system can reduce the main-lobe 3 dB width and suppressing the side-lobe peaks simultaneously. This is done by adjusting the number of sub-signals, frequency offset coefficient and the inter-element spacing. Then, through time slot processing, signal power is focused on different targets. Numerical simulation experiments are implemented to validate the theoretical analysis of the proposed methodology, and comparisons with other techniques are made.

“…Also in [15], time-modulated optimized frequency offset (TMOFO) is developed for obtaining better spatial focusing performance. Recently, multi-carrier architecture combined with nonlinear distributed frequency offset is proposed in [16] and pencil-shaped time-invariant beampattern is achieved.…”

“…Simulation experiments are carried out to evaluate the performance of the proposed approach. The results are also compared with the Multi-Carrier-FDA (MC-FDA) recently proposed in [16] and it turned out that the proposed FDA can provide improved spatial focusing performance with more effective side-lobe suppression simultaneously.…”

The basic frequency diverse array (FDA) using linearly increasing frequency increments generates a range-angle dependent beampattern. However, it is coupled in range and angle dimensions and is also periodic in range and time, making its applications limited. In this paper, a novel FDA beampattern synthesis approach is proposed utilizing the time-modulated double parameters based on the chaos sequence. The chirp signal mechanism is used instead of the single-frequency signal mechanism. Meanwhile, the multi-carrier architecture is used for range-angle decoupling. Satisfactory time-invariant range-angle beampattern can be synthesized for both single and multiple targets locations. Simulation results show the effectiveness of the proposed FDA scheme. Furthermore, comparative study with the existing technology indicates that the proposed approach can provide better performance in spatial focusing and side-lobe suppressing.
