Opportunistic positioning utilizing low Earth orbit satellite (LEO) signals mostly adopts Doppler positioning, the performance of which largely depends on accuracy measurement at receiver. Traditional methods for Iridium NEXT are limited and implemented in frequency domain, cannot avoid limitation fast Fourier transform operation. Aiming this problem, article proposes a method achieving accurate signal time namely phase-time method. This achieves by measuring change rate phase over time....
Oral multitarget tyrosine kinase inhibitors (TKIs), such as sorafenib, which suppress tumor cell proliferation and angiogenesis, have been approved to treat patients with hepatocellular carcinoma (HCC). Of note, only approximately 30% of can benefit from TKIs, this population usually acquires drug resistance within 6 months. In study, we intended explore the mechanism associated regulating sensitivity HCC TKIs. We revealed that integrin subunit β 5 (ITGB5) is abnormally expressed in...
Radar is an extremely valuable sensing technology for detecting moving targets and measuring their range, velocity, angular positions. When people are monitored at home, radar more likely to be accepted by end-users, as they already use WiFi, perceived privacy-preserving compared cameras, does not require user compliance wearable sensors do. Furthermore, it affected lighting conditions nor requires artificial lights that could cause discomfort in the home environment. So, radar-based human...
Abstract The development of castration‐resistant prostate cancer (CRPC) is a significant factor that reduces life expectancy among patients with cancer. Previously, it reported CDK4/6 inhibitors can overcome the resistance CRPC to BET by destabilizing BRD4, suggesting combination and promising approach for treating CRPC. In this study, candidates affect combined antitumor effect on aimed examine. data demonstrates CBX3 abnormally upregulated in inhibitors‐resistant cells. almost positively...
Opportunity positioning by low Earth orbit (LEO) satellite signals has been widely researched and developed as a supplement to global navigation system (GNSS). However, poor clock stability multiple consecutively received epochs' Doppler method really limit the LEO opportunity accuracy. To address problems, this article systematically analyzes best linear unbiased estimation (BLUE) of users' position under error significance priori information in terms accuracy improvement. Then novel mutual...
Recently, radar micro-Doppler signatures have been extensively utilized for hand gesture recognition. As reported by existing works, recognition accuracy of different gestures is heavily affected the aspect angle. In general, deteriorates significantly with increasing To solve this problem, we propose to utilize interferometric in paper, which capable providing two-dimensional micro-motions information, referred as radial and transversal micro-motions. We record data 9 4 angles, where three...
This paper investigates the problem of UAV detection and tracking using an interferometric radar. Different from various existing work in literature, UAVs are detected tracked by extracting information range 2-D velocities radar measurements. The radial velocity can be estimated performing respective fast-time slow-time FFT to collected data. However, it is insufficient track with only as do not usually fly straight along direction line sight (LoS). Fortunately, we estimate angular...
In the context of Global Navigation Satellite System (GNSS) denial environments, positioning can be achieved using Low Earth Orbit (LEO) satellite signals opportunity (SOP). When instantaneous visibility LEO satellites is insufficient, independent dynamic cannot realized, necessitating combination with Inertial Systems (INS) for positioning. However, in current research, LEO/INS integrated either requires initialization states GNSS/INS or demands a prolonged stationary period to utilize SOP...
This paper presents an approach for simultaneous tracking of multiple targets using the interferometric frequency modulated continuous wave (FMCW) radar. A dual-channel receiver FMCW radar is utilized measurement. The trajectory each target estimated separately based on two-dimensional position and velocity, which can be extracted by applying stretch processing time-frequency analysis to echo signals simultaneously. positions velocities are input a Kalman filter improve performance....
The linear velocity of an arbitrary moving target comprises two orthogonal components with reference to the observing radar, namely radial and transversal velocities. can be measured by interferometric radar directly. When measuring multiple targets, there exist cross-terms that have no physical meanings interfere extraction useful frequency. In this paper, we propose a new method utilizing uniform receiving array three antennas based on spatial averaging suppress measure targets...
Interferometry is considered as a computationally efficient and economically fair method for direction of arrival (DOA) estimation using limited number receiving antennas. Moreover, interferometric arrays are capable providing relatively high-accuracy estimates, with the sacrifice involving phase ambiguity byproduct large antenna spacing. In this work, we first propose line length matching (PLLM) unambiguous DOA estimation. Then, analyze performance three-antenna in both cases high low...
