This chapter discusses the techniques are known as direct holographic imaging methods since the phase of the scattered field is measured directly via vector measurement. It also dicusses the three‐dimensional (3D) holographic imaging can be referred to as quasi‐microwave holography. In general, the applications related to security screening have been the major motivation for developing microwave and millimeter‐wave holographic imaging. Millimeter‐wave holographic imaging for concealed weapon detection was originally proposed. The chapter describes the 2D synthetic aperture radar imaging technique. It examines wideband holographic imaging which is a means of forming 3D images of objects from wideband data gathered over a 2D aperture. The spatial sampling along the aperture is determined by a number of factors including the wavelength, the size of the aperture, the size of the object, and the distance to the object.
