“…Besides, [41] proposed an electronic countermeasure (ECM) system for OFDM-based passive radars and investigated in detail how the system generates and transmits multiple false target echoes for moving targets. In [42], the authors proposed transmit-adaptive jammer nulling waveforms for cognitive radar and introduced knowledge-based noise jammers in the electronic warfare. The simulation results indicate that the proposed transmit-adaptive waveforms have inhibitory effect on knowledge-based noise jammers.…”

In the environment of electronic warfare, the countermeasure between radar and jammer has become a hot issue. Finding the solution to optimal waveforms between them is very great significance. Aiming at the problem of multi-target detection in clutter environment, the authors propose the waveform optimization method based on signal-to-interference-plus-noise ratio (SINR) criterion for radar and jammer, respectively. When radar is the dominant player, the maxmin strategy is used to establish the optimization model to optimize the radar transmission waveform. When jammer is the dominant player, the minmax strategy is used to establish the optimization model to optimize the jammer waveform. When dealing with random multi-target, the authors also propose an adaptive weight method to solve the problem of summation of weighted multiple targets. Then, an improved method combined with Jensen’s inequality for radar and jammer is proposed, respectively, which could improve the detection performance of the radar system and reduce the computational complexity of maximum SINR-based method. The simulation results show that the proposed maximum SINR-based methods could adaptively allocate the transmission energy to improve the performance of the radar. The energy allocation of radar and jammer is slightly different under maxmin strategy and minmax strategy. The proposed improved methods could output the higher SINR than the maximum SINR-based methods. Both of the proposed methods could improve the performance of radar detecting targets.

“…In recent electronic warfare, high-power jamming systems have often been used to disrupt enemy radio frequency (RF) radar systems in vehicles, ships, and aircraft by transmitting broadband interference RF waves [1]− [4]. These highpower jamming systems require phase array antennas with broadband characteristics, since the various target RF devices typically operate in multiple frequency bands.…”

This paper proposes an all-metal Vivaldi array antenna with a wide-angle impedance matching (WAIM) layer for high-power jamming systems. To reduce fabrication complexity and time, the proposed array antenna is manufactured using a metal 3D printing method. The Vivaldi unit cell, composed of a radiating flare part and an inner cavity, is extended into an 8 × 8 array with a ±45° slant configuration. To further enhance the beam steering angle, the WAIM layer is placed on top of the proposed array antenna. The performances of the proposed array antenna, such as its active reflection coefficients (ARC), gains, and array radiation patterns, are investigated in a full anechoic chamber. At a steering angle of (0 = 45°, 0 = 25°), the measured and simulated average ARCs of the center element (Port 36) with the WAIM layer are -13.2 dB and -18.5 dB, respectively. At 4 GHz, the measured and simulated bore-sight gains of the proposed array antenna are 19 dBi and 20.6 dBi, respectively. In addition, the measured and simulated bore-sight gains for the (0 = 45°, 0 = 0°) steering angle in the zx-plane are 18 dBi and 21 dBi, respectively. In the zy-plane, bore-sight gains for the (0 = 45°, 0 = 0°) steering angle are 19.3 dBi by measurement and 19.1 dBi by simulation. These results demonstrate that the proposed array antenna is suitable for highpower jamming systems because stable bore-sight gains are observed even at wide steering angles without unwanted grating lobes.INDEX TERMS High-power jamming systems, 3D printing, all-metal Vivaldi array, unit cell array, wide angle impedance matching
