Special Issue Information

Dear Colleagues,

In recent decades, multi-sensor and multi-channel systems have attracted much attention from both academia and industry. Modern systems equipped with a range of sensors, multi-channel electronics, and advanced array processing capability have gained momentum in almost all application areas, including radar, mobile communications, underwater sonar, non-destructive evaluation, healthcare, sensing and imaging, wireless charging, and unmanned vehicles. The collaborative processing of multi-sensory and array data allows for many advantages and makes systems much more powerful, intelligent, flexible, robust, and reliable, usually with less cost. However, current sensor array systems and technology still suffer from critical challenges in order to meet ever-increasing demands and expectations. The recent advances in sensor design, new materials, electronics, array algorithms, computation, and artificial intelligence technologies have promising potential to overcome some of the key challenges.

Most of the challenges encountered in multi-sensor systems and technology still need to be researched, regardless of the applications. Many limitations exist in various application environments, and research questions remain open. This Special Issue provides a platform to share the most recent developments in this field, and we look forward to the latest research findings that suggest theories and practical solutions for various applications using array technology and systems.

Frequency-modulated continuous wave (FMCW) radar is widely used in automotive and consumer electronics because of its range, velocity, and angle measurement functionality. In an FMCW radar system, the isolation between transmitting (Tx) and receiving (Rx) subsystems affects the sensitivity of the FMCW system, which directly impacts the system’s overall performance in target detection. The factors that affect system performance include transmitter-to-receiver on-chip coupling and Tx-to-Rx antenna coupling. The on-chip isolation performance is basically fixed once a radar chip is given, but the antenna isolation performance depends on a designed antenna array. Usually, a targeted antenna requirement is first specified, and then the corresponding Tx and Rx antenna array is designed. However, there is no general principle or criteria for specifying a proper antenna isolation requirement in the existing research. In this paper, first, we reveal that the antenna isolation requirement should be set to be almost the same as the given on-chip isolation value, which is very significant as a general guideline in setting a targeted antenna isolation requirement. All current antenna isolation methods cannot reach the level of on-chip isolation in a compactly designed radar system. We further propose a teardrop-based method to provide high antenna isolation. The principle of an antenna isolation requirement and a novel antenna design using teardrops are both analyzed and demonstrated based on a representative 24 GHz FMCW radar. Our teardrop-shaped structure in the mouth of the conventional Vivaldi antenna achieved greater than 50 dB isolation, while the distance between the Tx and Rx antennas could be reduced to 2.1 mm.

This paper presents a method for the joint detection and direction of arrival (DOA) estimation of low probability of detection (LPD) signals. The proposed approach is based on using the antenna array to receive spread-spectrum signals hidden below the noise floor. Array processing exploits the spatial correlation between phase-delayed copies of the signal and allows us to evaluate the parameter used to make the decision about the presence of LPD transmission. The DOA estimation is based on the covariance between signals received by sensors for the fixed geometry of the antenna array. Moreover, the paper provides a method for mitigating narrowband interferences prior to signal detection. The presented methods were verified through simulations which proved that the confident detection of a one-second transmission in an additive white Gaussian noise channel is possible even when the noise is 24 dB higher than the power of the received signal. The performance of DOA estimation is analyzed in a wide range of signal-to-noise and interference-to-noise ratios. It is found that the DOA may be estimated with an RMS error not exceeding 10 degrees, even if interference occupies 15% of the analyzed frequency band. Full article
