ABSTRACT
Incoherent tomography is taken to mean tomography in the case when the radio-wave transmitter and receiver are not synchronized, so that the relative phase difference between the transmitted and received signals cannot be measured. Radio-holographic methods are considered to be a promising development of radio-tomographic systems in the terahertz and sub-terahertz bands, because they require measurements only of the field intensity and do not require any measurements of the phase. This chapter describes the highest-quality 3-D image with a resolution close to the diffraction limit that can be obtained with synthesis aperture radar (SAR) technology using ultra-wide band (UWB) signals. The weak point of the system of manual Doppler radio tomography is the need to apply a precise positioning subsystem to recalculate the experimental data to a uniform spatial grid. A design for a manual radio tomography based on Doppler motion sensors has been proposed.
