Abstract: Computer simulation is largely used in radar signal analysis. This present work treats the simulation of precipitation echoes in weather radar application. where two different approaches are used for simulating weather radar signals. These simulated signals offer great potential for estimating spectral moment and various polarimetric variables .One of the methods uses a time domain ap...

The microwave Doppler radar sensor enables a non-contact approach for measuring movement in various applications. One of the most challenging issues is radar signal demodulation because it requires accurate DC offset compensation. Existing works either require a complicated setup procedure or are sensitive to environmental changes. In this reported work, a compressed sensing based approach to e...

A complete centralized processing framework is proposed for human tracking using multistatic radar in the foliage-penetration environment. The configuration of the multistatic radar system is described. Primary attention is devoted to time of arrival (TOA) estimation and target localization. An improved approach that takes the geometrical center as the TOA estimation of the human target is give...

Subsurface formations with low compaction, often, due to the presence of underlying cavities, are potential sources hazards. Thus, understanding occurrence, properties, and extension these weak zones poses a major concern in engineering geophysics. In this study, we examine ability geophysical methods map areas over carbonates Northern Oman. The known cause surface depression many areas. examin...

due to increasing growth of air traffic, it is very important to have a reliable air traffic control system. usually secondary surveillance radar systems are employed for this task. in this paper, a new approach is presented to identify interrogators location of this system. the proposed method works passively and uses just a single receiver. this goal has been reached using angle and time diff...
