The three-dimensional instrument functions of synthetic aperture LFM-radar using MIMO-lines with different topologies are studied by means of numerical simulation. A comparison with usual synthetic aperture radar was carried out.
The modification of the algorithm for radio holographic synthesis of 3D-images based on probing LFM-signal is developed. The modification takes into account the effect of refraction at the boundary with a receiving environment. Double improvement in resolution and geometric similarity image subsurface objects are shown experimentally.
The experiment examines the performance of the logarithmic spiral antennas, Vivaldi antennas and dipole antennas when operating in continuous wave radar based on a chirp signal. Evaluation of the spectrums of the received signals shows that the use of the separation shield can effectively reduce mutual coupling. It also concluded the feasibility of constructing the antenna system holographic radar...
