Ground targets are constrained to move on the Earth's surface and are most likely to travel along a road network. For targets on road, their interaction with the environment and with each other particularly at intersections is more structured, thus useful to tracking algorithms. Indeed, the knowledge of terrain database and road maps can be used as(More)
With high-resolution radar sensors such as HRRR and SAR, ground targets become visible more as a rich set of radar signatures corresponding to the target geometrical details than as a single reflector with an equivalent RCS. This has enabled target classification and identification (ID). As a "by-product" of the target ID process, the pose angles are(More)
Target tracking performance is determined by the fidelity of target mobility model (F, Q), tracking sensor measurement quality (R), and sensor-to-target geometry (H). A tracking sensor manager has choices in sensor selection/placement (H), waveform design (R), and filter tuning (F and Q), thus affecting the tracking performance in many ways. This paper(More)
In this paper, we compare the information-theoretic metrics of the Kullback-Leibler (K-L) and Renyi ( ) divergence formulations for sensor management. Information-theoretic metrics have been well suited for sensor management as they afford comparisons between distributions resulting from different types of sensors under different actions. The difference in(More)
Using 3H-adrenalin the quantity and characteristics of the adrenalin receptors on human platelets were evaluated. Maximum adrenalin binding by intact platelets from eight normal subjects averaged 3.2 ng adrenalin/10(8) platelets, equivalent to 105 000 binding sites per platelet. Bound 3H-adrenalin could be dissociated or binding could be inhibited by an(More)
A new approach to the study of antiplatelet antibodies is described. Purified IgG from sera or from the culture of splenic ells was radiolabeled with 125I. Incubation of radiolabeled splenic IgG from ITP patients showed significantly greater binding to target platelets when compared to control IgG samples; conversely, the binding to target platelets of(More)
This paper analyzes the effects of special target-sensor geometries, particularly, some degenerate cases (near singular observation matrix), on the performance of target positioning and tracking. A scenario of practical significance is when two or more sensors form nearly parallel line of sight (LOS) vectors to targets. Examples include netted radars that(More)
