Millimeter-wave imaging is attracting increasing interest due to the non-ionizing nature of millimeter-wave radiation and the benefits that it entails for various emerging applications. This work uses a low-cost radar architecture that scans a commercial V Band multiple-input multiple-output (MIMO) radar sensor in several locations to synthesize a larger radar aperture. This paper presents the image reconstruction of two targets placed in different ranges with limited scanning and reduced aperture size to overcome the high overall system cost and weight associated with traditional multi-element apertures. We show simulated and experimental measurements by utilizing a 20TX/20RX single-board radar from 62 to 67 GHz.

In the realm of automotive technology, hands-free trunk operation systems have emerged as a cornerstone of convenience and functionality. Predominantly reliant on ultrasonic and camera-based sensors, these systems, however, falter in adverse weather conditions such as rain, snow, and fog, and are limited by short detection ranges and susceptibility to false alarms due to unintentional movements. Addressing these limitations, this paper proposes an innovative solution utilizing a 60 GHz frequency-modulated continuous wave radar sensor. This system is resilient in various weather conditions and has a robust detection mechanism for kick gestures. By employing two-dimensional fast Fourier transform for range and velocity analysis and an antenna array system for azimuth angle extraction, our radar sensor effectively discerns kick gestures. The data, once processed, is channeled through controller area network flexible data-rate communication to a deep learning classifier. This classifier, tested for accuracy, successfully identifies valid kick gestures with a remarkable 99.75% accuracy. Our findings present a significant advancement in sensor technology for smart trunk systems, paving the way for more reliable and efficient hands-free automotive operations.

In electronic warfare, effectively controlling the characteristics of targets to prevent them from being detected by radar is always a key issue in the field of target protection. This paper uses a phase modulation surface to regulate the target characteristics, enabling the radar to enter a repeated confirmation process. From the perspective of the consumption of radar search resources, the impact of target characteristic changes on the phased array radar search process is analyzed. This study has significant implications for the self-protection of targets and anti-identification in electronic warfare.

This paper addresses the challenges of the roadside sensing infrastructure in providing reliable vehicle classification and positioning data, and sharing said data with connected and automated vehicles. For this purpose, a novel sensor fusion model is proposed, fusing data streams from traffic classification radar and video camera, leveraging the best characteristics of each sensor. The goal is to extend vehicles' sensing horizon while enhancing object classification performance and disseminating data with neighboring vehicles via Collective Perception Message (CPM). Our model incorporates two Artificial intelligence (AI) models for object identification and data fusion. Experimental results indicate a 23.73% improvement over the native radar classification under optimal conditions, showcasing the model's efficacy. Comprehensive data analysis reveals the model's resilience under diverse conditions, outperforming radar and independent camera classifications. The fused model corrects camera errors, achieving superior accuracy, especially in nighttime scenarios. This research contributes to safer and more efficient cooperative driving experiences, demonstrating the effectiveness of the sensor fusion approach in varying environmental conditions.

The evaluation of cardiac activity is fundamental in determining an individual's health status. In this study, a contactless Doppler cardiogram (DCG) extraction method via frequency-modulated continuous wave (FMCW) radar sensor is proposed. The DCG provides information about cardiac movement, while the differential DCG (D-DCG) signal contains crucial points (CP), corresponding to specific waveforms of ECG. In order to extract DCG in indoor environment, a recursive least squares notch bank (RLSNFB) and moving average filter bank (MAFB) are proposed to adaptively and effectively remove breath signal and its harmonics, as well as high-frequency noise interference, while ensuring distortion-free representation of DCG in the time domain. Experiment with a 60GHz FMCW radar in a complex indoor environment demonstrates that the proposed method successfully extracts DCG from human and accurately locates CPs corresponding to ECG in the D-DCG.

This paper outlines opportunities and challenges for building missile seekers with the sensor Open Systems Architecture (TM) (SOSA) Technical Standard, Edition 2.0, Version 2 (Snapshot 2). In Section 1, two missile seeker instance architectures using the SOSA Technical Architecture are described, one for Electro- Optical/Infrared (EO/IR) and one for Radio Detection and Ranging (radar). Opportunities within the logical signal processing chain, including module functions, inter-module interactions, and messaging sets are discussed in Sections 2, 3, 4, and 5. Section 6 addresses the potential challenges in the physical layer due Size, Weight, and Power (SWaP) constraints on missile systems. In Section 7, some opportunities to support swappable seekers within the Modular Open Systems Approach (MOSA) ecosystem are outlined. The findings of this effort are summarized in the conclusion section.

In the realm of intelligent living, millimeter-wave radar is gradually finding application, leading to a heightened level of convenience. In this paper, a novel technique enabling real-time orientation of an electronic fan towards a human target based on a 77 GHz radar sensor system is proposed. Leveraging frequency-modulated continuous-wave (FMCW) multiple-input multiple-output (MIMO) radar theory and density-based spatial clustering of applications with noise (DBSCAN) algorithm, the radar system accurately acquires center angle related to the human target. Subsequently, the angle data is transmitted to the STM32 microcontroller via UART, facilitating the generation of a pulse width modulated wave for precise control of stepper motor rotation. The radar system not only accurately detects angle from a corner reflector, validating measurement accuracy but also successfully achieves real-time human presence sensing, dynamically adjusting the fan's rotation. The experiments show that the system can significantly implement the real-time rotation of the fan following the human body in the office environment.

This paper focuses on static source localization employing different combinations of measurements, including time-difference-of-arrival (TDOA), received-signal-strength (RSS), angle-of-arrival (AOA), and time-of-arrival (TOA) measurements. Since sensor-source geometry significantly impacts localization accuracy, the strategies of optimal sensor placement are proposed systematically using combinations of hybrid measurements. Firstly, the relationship between sensor placement and source estimation accuracy is formulated by a derived Cramer-Rao bound (CRB). Secondly, the A-optimality criterion, i.e., minimizing the trace of the CRB, is selected to calculate the smallest reachable estimation mean-squared-error (MSE) in a unified manner. Thirdly, the optimal sensor placement strategies are developed to achieve the optimal estimation bound. Specifically, the specific constraints of the optimal geometries deduced by specific measurement, i.e., TDOA, AOA, RSS, and TOA, are found and discussed theoretically. Finally, the new findings are verified by simulation studies.
