A new algorithm is proposed for phased array radar search function resource allocation. The proposed algorithm adaptively priorities radar search regions and in overload situations, based on available resources, radar characteristics, maximum range and search regions, optimally allocates radar resources in order to maximize probability of detection. The performance of new algorithm is evaluated...

Given the high throughput requirement for 5G, merging millimeter wave technologies and multi-user MIMO seems a very promising strategy. As hardware limitations impede to realize a full digital architecture, hybrid MIMO architectures using both analog and digital precoding are considered a feasible solution to implement multi-user MIMO at millimeter wave. Real channel propagation and hardware no...

This paper presents an approach that how to locate and to detect obstacle or hurdles or the human being or any living being, using synthetic aperture radar (SAR). The paper consist of the acknowledgement of idea how to trace the any moving object on earth level or above the earth level bye using GMTI(Ground Moving Target Indicator) or synthetic aperture radar SAR. It is demonstrated that SAR pr...

Vital sign monitoring plays a critical role in tracking the physiological state of people and enabling various health-related applications (e.g., recommending change lifestyle, examining risk diseases). Traditional approaches rely on hospitalization or body-attached instruments, which are costly intrusive. However, recent years there is an emergence contact-less vital techniques that radio freq...

Abstract: This paper proposes a novel scheme for multi-static passive radar processing, based on soft-input soft-output processing and Bayesian sparse estimation. In this scheme, each receiver estimates the probability of target presence based on its received signal and the prior information received from a central processor. The resulting posterior target probabilities are transmitted to the c...

The performance of multiple input multiple output (MIMO) radar configurations of distributed antennas are analyzed. Statistical multiple input multiple output (MIMO) radar develops angular diversity to mitigate the impact of radar cross section fluctuations (RCF). The fluctuations can be modeled with scattering model consists of non-orthogonal waveforms for fast target or radar cross section fl...

recently many studies have been done on different issues of using multiple antennas at transmit and receive sides of a radar system in a mimo (multiple input multiple output) configuration. in addition, for the electronic warfare‟s purposes, the utilization of available signals of the environment to detect the targets has gained considerable attention in recent years. such passive radars use th...

Multiple-input multiple-output (MIMO) techniques have brought significant advances to wireless communications. In recent years, researchers have sought to bring similar advances to radar using MIMO. One specific area that has received relatively little attention is MIMO synthetic aperture radar (SAR). The advantages that MIMO might provide to SAR are not well represented in literature. This pap...
