    Abstract:
    We demonstrate the design of a frequency-diverse aperture for imaging of human size objects. Frequency-diversity is an all-electronic technique, allowing the imaging to be performed without any mechanical moving parts or active circuit components. Leveraging computational imaging algorithms, the concept of frequency-diverse imaging offers a simplified alternative to conventional techniques limited in key metrics, such as data acquisition speed, system complexity and cost. It is shown that the synthesized-frequency diverse aperture can reconstruct good quality images of a human-size target by means of a simple frequency sweep over the K-band frequency regime.
