Abstract

This proposed project, focused on the development of SAR tomography processing algorithms, will be carried out in two fronts. For the first front, Radio Frequency (RF) and Microwave (MW) bands will be considered (P and L bands, in particular), aiming at underground tomography applications using a stepped-frequency SAR technique for a regular and noise/random probing signals for having a possibility to estimate refractive index for a single frequency (or narrowband) signal and use it at the next frequency step. In addition, this approach enables accounting frequency dispersions of the media. Novel strategies and related techniques for application of random/noise waveforms to drone-borne SAR design will be elaborated enabling high resistance against possible EM interferences. The second front will deal with the millimeter wave (mmW) and terahertz (THz) bands, aiming at human body tomography applications, via elaboration of a novel concept for the forthcoming sub-THz and THz short-range SAR sensors based on noise radar design using the "Stepped-Delay Noise Radar" concept. This approach exploits digital generation of both Tx signal and the properly tailored reference one for estimation of cross-correlation between the reference and radar returns in one channel analogue correlator, giving a possibility for design of a high-performance THz 'video-camera' for biomedical applications.
