Interstellar radar is a potential intermediate step between passive observation of exoplanets and interstellar exploratory missions. Compared with passive observation, it has the traditional advantages of radar astronomy. It can measure surface characteristics, determine spin rates and axes, provide extremely accurate ranges, construct maps of planets, distinguish liquid from solid surfaces, fi...

One of the most important functions of a radar antenna is to provide spatial filtering that maximizes the radar's sensitivity in the desired sUIveillance direction while suppressing interference signals that enter the radar from other directions. This article describes a UHF radar antenna systemwith exceptional interference-rejection capabilities that are achieved through a combination of preci...

Abstract—Space-Time Adaptive Processing (STAP) algorithm has recently been used in Passive Bi-static Radars (PBR) because it removes the clutter and non-cooperative transmitter effectively making the target detection easy in harsh environments like air-ground. Realtime implementation of STAP is a very challenging task as it is computationally-intensive, time-critical and resource-hungry process...

We present two stochastic filters for an FM-band passive air surveillance radar. The first system uses an extended Kalman filter and delay-Doppler measurements to track targets. The second system uses a particle filter to simultaneously track and classify targets. Automatic target recognition is made possible by the inclusion of radar cross section (RCS) in the measurement vector. The extended ...

Conventional civil Air Traffic Control (ATC) systems are able to detect targets and identify collaborative aircrafts in the air space but they don’t ensure full coverage at low altitudes, in presence of non-cooperative targets (NCTs) and aircraft (A/C) with a low value of radar cross section (RCS). This paper describes the ARGUS 3D (AiR GUidance and Surveillance 3D) project funded by the Europe...

The remote measurement of physical or chemical quantities from the wireless reading of active electronic devices with integrated sensors is no more a major issue. Such devices with sensing, identification and communication capabilities can be used as nodes of a network and, more generally, part of the Internet of Things. Passive (batteryless) sensors could be used as sensing nodes in order to e...

n today’s society almost everyone has a cell phone attached at the hip, and somewhere a television or radio is blaring. These everyday items may sometime soon aid in national defense. They will do so because a large component of defense comes from radar systems which depend on the same electromagnetic radiation that cell phones, televisions, and radios do. As a result of the growing prevalence ...

Scientists have explored that WiMAX has the potential to enhance the performance of the radar networks. With the idea of implementing MIMO (multi-input multi-output) communication technology for overcoming the challenges offered by hostile channel and environmental effects.It leads the technocrats to utilize this technology in radar operations. WiMAX MIMO can exploit the range of WiMAX and the ...
