Biological echoes are treated as contamination like ground or sea clutters by radar meteorologists as they estimate rainfall intensities or assimilate radar reflectivity into numerical forecast model. Doppler velocity measured by radar in the presence of small insects well represents air motion because small insects are considered as passive tracers. But in the presence of birds especially migr...

In this work, a wideband airborne reflector-based ground penetrating radar (GPR) is designed and proposed. The proposed GPR consists of 15 discrete panels, each panel supported by single multi-rotor unmanned aerial vehicle (UAV). A lightweight, Vivaldi antenna was developed as the feed structure. operates within frequency range 100-500 MHz has bandwidth 387 MHz. will possess penetration depth 2...

Introduction: As NASA's exploration plan for Mars advances with additional missions, the type and abundance of data increase. High-resolution images are revealing numerous wind-related features and suggest widespread distribution of aeolian deposits. These deposits reflect the current and past wind regimes on Mars, but they also obscure some of the bedrock geology. A complementary experiment to...

Synthetic Aperture Radar (SAR) measurements are unique for mapping forest 3D structure and its changes in time. Tomographic SAR (TomoSAR) configurations exploit this potential by reconstructing the radar reflectivity. The frequency of is one main parameters determining information content reconstructed reflectivity terms penetration sensitivity to individual vegetation elements. This paper atte...

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...

Deployment of a ground penetrating radar (GPR) on flying machine allows one to substantially extend the application area this geophysical method and simplify carrying out large surveys dangerous hard-to-reach terrain, where usual ground-based methods are hardly applied. There is necessity promote investigations in direction by modifying hardware characteristics developing specific proceeding al...

Ground-penetrating radar (GPR) is becoming a commonly applied technique in geomorphology. However, its use in the study of subglacial bedforms has yet to be fully explored and exploited. This paper presents the results of a GPR feasibility study conducted on a drumlinized terrain in Cumbria, UK, where five drumlins were investigated using multiple radar antenna frequencies. The site was selecte...

Autonomous off-road navigation is central to several important applications of unmanned ground vehicles. This requires the ability to detect obstacles in vegetation. We examine the prospects for doing so with scanning ladar and with a linear array of 2.2 GHz micro-impulse radar transceivers. For ladar, we summarize our work to date on algorithms for detecting obstacles in tall grass with single...

Affected by natural and human-induced factors, cultural heritage sites and their surroundings face threats of structural instability and land displacement. Accurate and rapid identification of the key areas facing existing or potential deformation risks is essential for the conservation and sustainability of heritage sites, particularly for huge archaeological regions. In recent years, the succ...
