This paper presents an in-depth analysis of the Linear Frequency-Modulated Continuous-Wave (LFMCW) radar, focusing on its application in urban environments for detecting low, slow, and small (LSS) targets. The paper comprehensively examines the operational range, noise characteristics, system loss, error sources, and various signal processing schemes of LFMCW radar. Special attention is given to the array radar technology, emphasizing its significance in modern radar systems and how it enhances target detection through techniques like Intermediate Frequency Quadrature Sampling, Amplitude and Phase Error Correction, Target Parameter Estimation, and Constant False Alarm Rate Detection. The research underscores the system's capability in simultaneous multi-beam formation, crucial for accurate target detection and angle measurement in challenging urban scenarios. The findings indicate that LFMCW radar, equipped with advanced signal processing techniques, offers robust performance in detecting LSS targets, making it highly suitable for applications in areas like airport airspace control, military surveillance, and public event security.

Orthogonal time frequency space-integrated sensing and communication (OTFS-ISAC) has recently emerged as a focal point of research within the development of sixth generation (6G) networks, due to its unique advantages in high mobility scenarios. In this article, we focus on the parameter estimation problem of sensing targets in the OTFS-ISAC system. Firstly, we introduce the system framework of OTFS-ISAC. Then, a review is conducted on the parameter estimation methods of sensing targets in OTFS-ISAC. Furthermore, technical challenges that OTFS-ISAC may face are outlined, as well as the future research directions. Finally, we provide several emerging applications for OTFS-ISAC and make statements on the parameter estimation of sensing targets in these scenarios.

Floating marine debris is one of the significant marine pollutions that affect many living on the globe. Thanks to satellite technology, the Earth observation satellite has mostly constant frequency and wide area coverage. Moreover, some observation data are also openly and freely accessible for everyone, such as Sentinel platforms' data. However, most floating debris is difficult to observe by the above platform because it often has a smaller size than the highest spatial resolution of the Sentinel data. In this paper, we propose the method for detecting the floating marine debris via the Sentinel-2 data. The infrared normalized difference vegetation index (INDVI) was modified to increase plastic debris detection capability. The narrow near-infrared band (band 8A) was replaced by the highest near-infrared band (band 8). Two individual formulas of the modified version were proposed due to the INDVI is an empirical formula dependent on each platform sensor. The known targets of the floating plastic aggregation from two valuable experiments at Tsamakia beach, Greece, and Limassol old port, Cyprus, were used to observe and evaluate the detectable capability. The signal to Noise Ratio (SNR) was applied to indicate our method performance compared with many recent methods of floating plastic debris detection. The results show that our proposed method can be well used to detect floating aggregated plastic objects, although it has a small size than the Sentinel-2 spatial resolution. Besides, it can also observe some floating plastic patches that are difficult to notice by visible optical information. © 2021 IEEE.

This paper presents a system-level description of the Joint Services Lightweight Standoff Chemical Agent Detector (JSLSCAD). JSLSCAD is a passive Fourier Transform InfraRed (FTIR) based remote sensing system for detecting chemical warfare agents. Unlike predecessor systems, JSLSCAD is capable of operating while on the move to accomplish reconnaissance, surveillance, and contamination avoidance missions. Additionally, the system is designed to meet the needs for application on air and sea as well as ground mobile and fixed site platforms. The core of the system is a rugged Michelson interferometer with a flexure spring bearing mechanism and bi-directional data acquisition capability. The sensor is interfaced to a small, high performance spatial scanner that provides high-speed, two-axis area coverage. Command, control, and processing electronics have been coupled with real time control software and robust detection/discrimination algorithms. Operator interfaces include local and remote options in addition to interfaces to external communications networks. The modular system design facilitates interfacing to the many platforms targeted for JSLSCAD.

Wavefront Adaptive Raymode processing for Over-the-Horizon HF Radar Clutter Mitigation

Wavefront Adaptive Raymode Processing for Over-the-Horizon H...

Asilomar conference on signals, Systems & Computers

作者： Oguz Kazanci Igal Bilik Jeffrey Krolik Department of Electrical and Computer Engineering Duke University Durham NC USA

Detection of surface targets using over-the-horizon radar (OTHR) is extremely challenging due to ionospherically-induced Doppler spread clutter. In particular, low Doppler targets are often masked by ground clutter arriving via multipath propagation at different elevation angles, each with a different ionospheric Doppler shift. The wavefront adaptive raymode processing (WARP) approach presented here exploits the azimuthally distributed nature of the clutter return and adaptively estimates the "crinkly" spatial wavefront arriving on each raymode by using its distinct Doppler spectral characteristics. Rather than the plane-wave beamwidth of the array aperture, the raymode resolution of WARP is limited by the wavenumber-extent-spatial-aperture (WESA) product of the clutter return. Thus it is possible to spatially separate clutter raymodes using limited array apertures. Using simulated radar data, WARP is shown to provide a signal-to-clutter-plus-noise ratio (SCNR) improvement of as much as 30 dB over conventional processing for targets buried in Doppler spread clutter.

International conference on Acoustics, Speech, and signal processing (ICASSP)

The traditional direct position determination (DPD) for multiple targets usually requires transmitting raw data to the fusion center (FC), which occupies large transmission bandwidth and hardware resource. To solve this problem, we adopt one-bit analog-to-digital converters (ADCs) for a distributed subarray (DS) system, and propose an one-bit DPD method with multiple signal classification (1-bit DPD-MUSIC). The method approximates the one-bit signal as a scaled infinite-bit signal with a quantization error. Thus, the MUSIC algorithm can be straightforwardly applied without extra preprocessing. Simulations demonstrate that the proposed method saves large bandwidth and power with a slight loss of performance compared with the infinite-bit one. Moreover, 1-bit DPD-MUSIC is computationally efficient and outperforms the one-bit DPD based on maximum likelihood estimate (MLE) one for the close targets.

In dual-sensor multi-target data processing, it is crucial to pair the measurements originating from the same target. Up to now, a number of algorithms have been developed to deal with the issue. However, the local methods among them perform poorly in dense target scenarios, while common global algorithms are difficult to implement because of their huge computational complexity. In this paper, an efficient global method is proposed to deal with the measurement pairing of dense targets in a dual-sensor system. Referring to maximum a posterior probability(MAP) criterion, we show that the optimal pairing scheme is the one that minimizes the quadratic sum of the Euclidean distances between the paired measurements. Therefore, we convert measurement pairing into an assignment problem, which is a typical NP-hard issue in combinatorial optimization. The Hungarian algorithm is adopted to solve the converted problem and the simulation results verify the effectiveness of the proposed method.

作者： Hasan İhsan Turhan Mübeccel Demirekler Orta Dogu Teknik Universitesi Ankara Ankara TR

This study proposes a multi-dimensional Hough transform algorithm that is improved from by detecting weak targets in the high clutter. In the proposed algorithm execution time is reduced by eliminating the measurements considering speed and SNR values before the Hough transform. The skor-based track confirmation algorithm proposed is improved and tracks that belong to same target are eliminated. The proposed algorithm is tested with real data and results are presented.
