This study proposes an algorithm to improve the target localization performance. is implemented in a multiwaveform multiband hybrid (passive and active) multistatic radar network scenario that utilizes broadcasting signals for sensing addition waveforms. Multiwaveform receivers can exploit broadcast transmitted by noncooperative transmitters, such as communication or systems, waveform. Hence, m...

Previous studies have shown that the localization of the perceived onset position of a moving target varies with the trial context. When the moving target appeared at predictable positions to the left or right of fixation (constant context), localization judgments of the perceived onset positions were essentially displaced in motion direction (Fröhlich effect). In contrast, when the target appe...

The accuracy of centroid localization based on the connectivity information between a target node and multiple randomly scattered reference nodes is investigated. First, the accuracy of the centroid localization is analyzed in a general fading environment and it is shown that the ambiguity area of this localization technique is inversely proportional to the density of the reference nodes. Addit...

many different radiolabeled antibodies have been used for radioimmunotherapy and radioimmunoscintigraphy of human diseases in animal experiments. in order to study the in vivo tissue distribution of antibody, we labeled human nonspecific polyclonal igg with na125i using chloramine-t method. an animal model was developed by injecting turpentine in the posterior left thigh of balb/c mice. tissue ...

To address the limitation of the existing UAV (unmanned aerial vehicles) photoelectric localization method used for moving objects, this paper proposes an improved two-UAV intersection localization system based on airborne optoelectronic platforms by using the crossed-angle localization method of photoelectric theodolites for reference. This paper introduces the makeup and operating principle o...

A localized surface plasmon resonance (LSPR) biosensor using surface relief nanostructures was investigated to evaluate the importance of target localization on the sensitivity enhancement. The LSPR device was modeled as periodic metallic nanowires with a square profile on a gold film and the target as a self-assembled monolayer in buffer solution. The numerical results using rigorous coupled-w...

Abstract – A practical recursive linear robust estimation scheme is proposed for target localization in the sensor network which provides range difference of arrival (RDOA) measurements. In order to radically solve the known practical difficulties such as sensitivity for initial guess and heavy computational burden caused by intrinsic nonlinearity of the RDOA based target localization problem, ...

In this paper a two-phase compressive sensing (CS) and received signal strength (RSS)-based target localization approach is proposed to improve position accuracy by dealing with the unknown target population and the effect of grid dimensions on position error. In the coarse localization phase, by formulating target localization as a sparse signal recovery problem, grids with recovery vector com...

This paper addresses the problem of robust target localization in distributed multipleinput multiple-output (MIMO) radar using possibly outlier range measurements. To achieve robustness against outliers, we construct an objective function for MIMO target localization via the maximum correntropy criterion. To deal with such a nonconvex and nonlinear function, we apply a half-quadratic optimizati...

This paper studies a multi-target localization method for distributed Multiple-input Multiple-output (MIMO) radar. We assume that the sets of time delays have already been estimated by a pre-processing algorithm. Based on the assumption, we propose a search pairing method based on ellipse model to locate the multi-target. Simulation results demonstrate that the proposed method effectively accom...
