Intelligent Sky Guardians (InSkyGuard): An Aerial Robotic Swarm for Autonomous Detection and Entrapment of Rogue Multirotors

Advanced Robotics Research, EarlyView.
Intelligent Sky Guardians (InSkyGuard) is introduced as a four‐drone swarm that autonomously detects, tracks, and safely captures rogue drones using a coordinated net system. Computer vision and leader–follower control architecture enable synchronized enclosure, while integrated failsafes enhance system reliability. Validated through closed‐environment

A review of the use of radio-echo sounding in glaciology

Progress in Physical Geography, 2001
Radio-echo sounding (RES), or radar, is an established geophysical technique that has been, and continues to be, applied to investigate a variety of ice-mass properties. This review presents the physical theory and principles of radio-glaciology, and describes the various types of radar equipment commonly used, including modern, ground-penetrating ...

Radio echo sounding of sea ice

Ocean '74 - IEEE International Conference on Engineering in the Ocean Environment, 1974
1. Morphological structure and state (i.e. temperature, salinity) of drifting sea ice are discussed. 2. The results of laboratory and natural investigations of UHF electromagnetic characteristics ( and tg ) of drifting sea ice are given. The estimate of electromagnetic contrast on ice-sea water boundary is given. 3.

Dry–Wet Bedrock Interface Detection by Radio Echo Sounding Measurements

IEEE Transactions on Geoscience and Remote Sensing, 2010
In this paper, a method to distinguish a wet or dry bedrock-ice interface is proposed. It is based on the analysis of radio echo sounding (RES) measurements, a widely employed method for determining bedrock topography in Antarctica. In particular, the RES system has played an important role in subglacial lake exploration and hydrogeological studies at ...

Progress report on radio echo sounding

Polar Record, 1967
This report is intended to summarize activities in radio echo sounding since the introductory paper which appeared in the Polar Record four years ago (Evans, 1963 a). The field work since that time is discussed in rough chronological order, with references to the sources of more detailed information and an assessment of the principal results.
