A radar system is generally implemented and addressed to detect the target of concern. So, in a radar system, analysis and application of Ultra Wide Band (UWB) signals solves most of the problems of radar target detection. Since multiple-input multiple-output (MIMO) radar possess significant potentials for fading mitigation, resolution enhancement and interference and jamming suppression, by op...

A real-time S-band radar imaging system will be shown in this paper that uses a spatially diverse antenna array connected to a highly sensitive linear FM radar system and uses a synthetic aperture radar (SAR) imaging algorithm to produce real-time radar imagery. The core of this radar system is a high-sensitivity, range gated, radar architecture. Previous work has demonstrated the effectiveness...

This paper describes the theoretical basis and conceptual design of a dual-frequency radar and microwave link (radar/link) system capable of measuring simultaneously forward and backscatter from rainfall. The forward and backscattering radar/link system will enable small-scale rain studies essential in understanding the rainfall process, and make significant contributions to the investigation o...

Frequency-Modulated Continuous-Wave (FMCW) Radar has traditionally been used in short range applications. Conventional FMCW radar requires the use of expensive microwave mixers and low noise amplifiers. A uniquely inexpensive solution was created, using inexpensive Gunn oscillator based microwave transceiver modules that consist of 3 diodes inside of a resonant cavity. However these transceiver...

Responsive Adaptive Display Anticipates Requests (RADAR) is a domain general system that learns to highlight an individual’s preferred information displays, given the current context. Previous studies with human subjects in a video game environment demonstrate that RADAR is an effective cognitive aid. RADAR increases situation awareness and reduces cognitive load by anticipating and providing t...

To achieve the important tactical requirement of low probability of intercept (LPI) in the complex radar network, dynamically controlling the emission of the radars is very necessary. A novel radar dwelling time control strategy based on an interacting multiple model algorithm is presented in this paper, which controls the dwelling time of radar according to predicted covariance matrix during t...

In this Chapter, a short range radar system based on ultra-wideband (UWB) technology is presented. The radar and its applications were reserved during a long time to national defence, air security or weather services domains. Since a few years, with the emergence of new technologies, the radar applications were developed and become known in many sectors of daily life. The arrival of a new techn...

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...

ELINT/ESM type of electronic intelligence in the primary layer uses parameters measurements of intercepted radar signals. Nowadays modern radar uses more and more complex waveforms. Some waveforms are developed intentionally to make their intercept almost impossible. The main distinctive features of modern radar signal are hidden in its time-frequency structure. In the near past the problem of ...

Radar data is routinely transmitted in real-time from the coterminous United States (CONUS) radar sites and placed on the Internet for incorporation into nowcasting, hydrology and modeling applications in near-realtime. Radar data are also archived for on-demand retrieval by the National Climate Data Center (NCDC). Data compression is used operationally to reduce bandwidth and storage requireme...
