abstract = "Three-dimensional (3D) remote imaging may improve target characterization and help improve tracking and aim-point maintenance. Digital holography (DH) has been shown to be very effective in generating 3D images of objects using frequency diversity. The digital holographic nature of the process can eliminate the need for imaging lenses when the pupil-plane is used for the detection plane. In fact, this approach is the optical analog of the widely used frequencymodulation (FM) radar imaging. The current implementation of the holographic FM 3D imaging involves forming a set of holographic 2D images each at a different temporal frequency and then inverse Fourier transform to recover the actual 3D image. In this paper we present results from both laboratory and simulations of a coherent 3D holographic imaging method based on continuous frequency chirping of a laser. Laboratory 3D imaging results were obtained in both the pupilplane using a spatial heterodyne method, and in the image-plane using a temporal heterodyne method.",
