System and method for radio frequency penetration imaging of an object
First Claim
1. A RF (Radio Frequency) imaging system, for imaging at least one object within a target medium, the system comprisinga generation and reception subsystem configured to generate and receive a plurality of RF signals;
- an RF antenna array, the RF antenna array comprises a plurality of antennas, said plurality of antennas are configured to transmit the plurality of RF signals towards the target medium and receive a plurality of RF signals reflected from the target medium;
a data acquisition subsystem configured to receive and store said plurality of reflected RF signals; and
at least one processor, said at least one processor is configured to;
estimate the distance between the surface of the target medium and the antenna array;
estimate the delay between the plurality of transmitted signals and the plurality of signals reflected from the at least one object, wherein the delay is estimated using a dedicated frequency sub-band of the received signals;
estimate the location of the plurality of antennas at each transmitting time; and
provide an image of the at least one object location and the intensity of the plurality of reflected RF signals.
