1. A broadband radio frequency (RF) imaging device comprising:
a broadband RF aperture array comprising a differential segmented aperture (DSA) having at least four array elements and having a bandwidth of at least 700 MHZ;
at least one RF receiver; and
a computer;
wherein the at least one RF receiver is configured to digitize broadband RF signal data received by the broadband RF aperture array to generate digitized broadband RF signal data; and
wherein the computer is programmed to reconstruct an RF image from the digitized broadband RF signal data.
