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 ...
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.
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 ...
