Against the range-dependent accuracy of the tracking radar measurements including range, elevation and bearing angles, a new hybrid adaptive Kalman filter is proposed to enhance the performance of the radar aided strapdown inertial navigation system (INS/Radar). This filter involves the concept of residual-based adaptive estimation and adaptive fading Kalman filter and tunes dynamically the fil...

Pharmaceutical manufacturers decry the purported burdens imposed by Federal regulation when it suits their proprietary interests, yet they sing a wholly different tune when defending product liability suits. As product liability defendants, they unabashedly seek the protective womb of Food and Drug Administration (FDA) regulation, arguing that agency approval of their drug and its labeling prec...

Target tracking and missile tracking radars and the radar test set on a block. Function of the acquisition radar system and the TTR and target ranging radar.in location-aware systems and services. In this paper we present RADAR, a radio-frequency RF based system for locating and tracking users inside buildings.dent laboratory model of the radar system that can be used for monopulse tracking. Ur...

This paper presents an investigation into the challenges in implementing a hard real-time optimal nonstationary system using General Regression Neural Network (GRNN). This includes investigation into the dynamics of the problem domain, discretisation of the problem domain to reduce the computational complexity, parameters selection of the optimization algorithm, convergence guarantee for real-t...

Abstract On the background of air defense missile which use radar command guidance, this article focuses on maneuvering target trajectory simulation and tracking problem by considering possible modes overload. Taking Serpentine (S maneuvering) as an example, is simulated based overload using stepwise design method, data are measured through sensor models. Since single model cannot motion exactl...

dezful a city at the far north of khuzestan on the southwest of the great iran is considered as an agriculture pole. this city as one of the iranian ancient cities was under hostile attacks of the iraqi ba’athist enemy throughout the holy defense era from 1980 to 1988 and during the five stages of the war of cities, in particular. so, in most of the enemy aerial and ground attacks against 127 i...

The purpose of the article was to find inner properties and regularities anti-aircraft missile grouping’s air defense battle, based on these develop evaluate adequacy models as tools for forecasting results a battle. To achieve goal, an example real battle special model development method were used. made it possible identify main law select statistically valid mathematical modeling tool in clas...

The article provides an analysis of the state affairs in field U.S. missile defense, inherited by Biden administration from previous administration. U. S. defense policy can be roughly divided into three components: homeland regional and advanced developments related to these both parts. Conclusions are made about prospects policy, taking account such factors as views experts think tanks close ...

Safety critical interactions increase as the complexity of highly integrated systems increases. In complex systems and systems-of-systems, these possible combinations are practically limitless. System “unravelings” have an intelligence of their own as they expose hidden connections, neutralize redundancies, bypass firewalls, and exploit chance circumstances for which no system engineer might pl...
