Three methods of producing microwave images of rotating objects are reviewed and correlated. These are range Doppler processing, coherent tomographic imaging, and a physical optics‐based technique using the Bojarski identity. We use an understanding of these processes to interpret and predict the appearances of images reconstructed from data collected over specified frequency and angular windows. Based on the understanding of the fundamental image formation processes, we have developed several image reconstruction algorithms applicable when objects are situated in different environments. Examples are bistatic imaging, near field imaging, moving target imaging, irregularly spaced array imaging, and imaging of objects embedded in a homogeneous dielectric background. Numerical and experimental results have verified the effectiveness of our proposed algorithms.©1993 John Wiley & Sons Inc
