Abstract: Traditional active radars transmit a powerful electromagnetic pulse and record the echo's delay time and power to measure target properties of interest, such as range, velocity, and ...
This chapter covers active sensing of the atmosphere using both ground-based and satellite-borne radars. Owing to the vast expanse of weather, hydrometeors, and atmospheric gases, in situ measurements ...
The European Space Agency’s launch of the Sentinel-1 satellite has made 20-meter resolution radar imagery of the whole planet freely available. The “all-weather, day-and-night supply of imagery of ...
Recent analysis of 2012 airborne radar data NASA collected remotely suggests the data could predict large sinkholes before they occur, such as one that caused evacuations near Bayou Corne, Louisiana.
According to Rice University research, EyeDAR, a low-power millimeter-wave radar sensor roughly the size of an orange, could ...

Satellite imaging is now vital for disaster management. But there are dangerous gaps in our systems
Satellite remote sensing allows rapid, detailed disaster response and planning. But the rules governing who controls and has ...
Active sensing encompasses the use of a transmitter and at least one receiver to measure (sense) the transmission or scattering properties of a medium at radio frequencies. In transmission ...
