Adaptive Radar Beamforming for Interference Mitigation in Radar-Wireless Spectrum Sharing

Abstract: The key to the feasibility of spectrum sharing between radar and wireless systems is effective mainlobe interference mitigation processing by the radar. Traditional array processing is capable to cancel sidelobe interferences only. This letter presents an innovative beamforming approach, the first of its kind, to eliminate wireless interference in both mainlobe and sidelobe directions based on a coherent phase-coding multiple-input multiple-output (MIMO) radar platform. The theoretical proof and conditions of … Show more

“…On the other hand, the aim of the wireless communication technique is to achieve the maximum information capacity over a noisy channel [1][2][3]. e works of [4][5][6][7][8][9] showed a possibility of employing the radar-communications integration concept to solve the lack of radio frequency (RF) spectrum. E cient utilization of shared bandwidth between wireless communications and radar can be achieved by using dynamic frequency allocation.…”

“…Furthermore, the network association was formulated as a signal-to-interference-plusnoise ratio (SINR) maximization problem at the radar receiver, which was also subjected to the rate and power constraints of the communication system by Li et al [9]. In [10], an adaptive radar beamforming technique was proposed by Geng et al for eliminating the wireless interferences imposed by communication systems during spectrum sharing. Furthermore, sophisticated interference mitigation methods were designed in [12], [13].…”

“…Spectrum congestion and interference between systems is a modern problem that tends to get worse because of the growth of new applications and their demand for greater bandwidths . Many alternatives have been proposed to deal with the coexistence of radar and communications, eg, interference mitigation techniques, spectrum sharing of radar and communications, and dual‐functionality platforms, where waveform and sensors are jointly managed for both radar and communication functions …”
