The literature of radar contains results Rice, Marcum, Swerling, and Schwartz in several families curves, which permit engineersto estimate the signal energy ratio required for a given level detectionperformance. variety problems, however, makes itimpractical to construct curves all combinations targetparameters. concept detector loss is used here evaluate lossesattributable integration collapsing, with an accuracy ±0.3 dBon steady targets. This added separate fluctuation loss, modifiedfor...
Land clutter reflectivity has been described in the literature for many types of terrain, viewed by radars different frequencies at grazing angles. Significant gaps remain published data, especially ground-based viewing terrain incidence, and bistatic situations where one path is incidence. An analytical model proposed here which predicts observed trends as functions range, antenna height, roughness, radar wavelength. By comparing measured data to model, better correlations among sets taken...
This issue of RMP has, as a special supplement, the report an APS study group on physics and engineering issues that must be addressed in designing missile defense system capable intercepting hostile while it is still burning, so-called ``boost phase.'' The challenges for boost-phase intercept are significant, chiefly because short time window during which detection, decision, launch, interception occur. Some aspects problem have not previously been analyzed such depth public domain. was...
In machine tools, Industry 4.0 functions can increase availability through predictive maintenance, while other improve productivity and workpiece quality process supervision optimisation. Many of these rely on data communication between systems from different suppliers. Requirements regarding latency computing vary widely depending the application. Based an analysis requirements, a smart controller for implementation is designed, using hypervisor to allow integration soft real-time...
An important aspect of the overall quality machined parts is surface roughness, which depends on cutting parameters, tool condition, and machine vibrations. Online roughness prediction in milling operations can reduce set up time assist determining economic parameters. However, adoption existing solutions industrial production inhibited by lacking integration an open retrofittable architecture. In this contribution, a solution for estimation vibration monitoring developed as part...
Sclerostin antibody (Scl-Ab) is an anabolic bone agent that has been shown to increase mass in clinical trials of adult diseases low mass, such as osteoporosis and osteogenesis imperfecta (OI). Its use decrease fragility pediatric OI efficacy several growing mouse models, suggesting translational potential disorders mass. However, the effects pharmacologic inhibition sclerostin during periods rapid growth development have not yet described with respect cranium, where lifelong deficiency...
The history of development monopulse radar in the US is reviewed herein. Significant techniques that permitted tracking radars to achieve accurate with high efficiency are discussed, including sum-and-difference antenna feed networks, multi-horn and multi-mode feeds, precision mechanical pedestals, space-fed arrays. discussion concentrates on surface-based radars, but many apply airborne missile seekers developed during same periods.
A theoretical model of diffuse multipath reflections from rough surfaces is applied to the prediction power distribu tions in radar coordinates: elevation angle, time delay, and Dop pler frequency. These distributions are used predict tracking errors for both monopulse scan ning antenna systems, typical results presented. show a small increase error scanning on radially approaching targets, caused by sensitivity these trackers amplitude scintillation composite direct-plus signal.

During the past several decades, Soviet Union investment in air defense systems has exceeded that of Western nations. New relationships with West have provided opportunities for us to see aspects a new generation Russian radar engineering not previously evident, some surprising results. A few these are described, areas surface-to-air missile control using types phased arrays, unlike those developed US and allied countries. The major features systems, differences from design practices, discussed.
