The International Legal Framework on the Utilization of Remote Sensing Satellites in the Event of a Disaster: Analysis of the Copernicus Emergency Management Service and its Contribution in the Response to the Wildfire in Chile

The aim of this contribution is to stress the importance of the use of remote sensing satellites within the framework of regional and international cooperation to improve responses to natural and human-made disasters. Starting from a comprehensive review of the international legislation underlying the satellite remote sensing activities, which has promoted the use of these technologies in emergency scenarios, the article will proceed, analyzing a practical case, with a technical explanation o...

OFDM Radar Onboard Moving Platform for GMTI

Typical scenarios for Integrated Sensing and Communication (ISAC) involve networks of moving nodes, such as UAVs, aircraft, or vehicles, that transmit waveforms enabling both inter-node communication and radar-based surveillance. In this context, Orthogonal Frequency-Division Multiplexing (OFDM) waveforms offer a unified solution for supporting wireless communication alongside ground moving target indication (GMTI), i.e., the detection of targets moving on or above the surface across wide mon...

OFDM Radar Based on Communications Signals of Opportunity

This chapter illustrates innovative signal processing techniques and architectures for radar systems based on the exploitation of opportunistic communication signals, namely WiFi and DVB-T OFDM signals. It covers three different applications and operational scenarios where these systems can be effectively employed for surveillance purposes, namely (i) short range monitoring based on WLAN transmissions, (ii) radar systems on board of moving platforms, and (iii) low-cost forward scatter radar s...
