Abstract

We discuss a 3D imaging modality called pulsed heterodyne-array imaging (PHI). The relationship between PHI and stepped-frequency methods for 3D coherent image formation is derived. For both cases, we consider flood-illumination of the object and detection with a 2D array of coherent receivers located in the pupil plane. It is shown that PHI can recover the same coherent 3D image as a stepped-frequency method such as holographic laser radar.
