Microcrystals of ammonium trivanadate with belt-like morphology of particles have been synthesized by hydrothermal treatment of NH 4 VO 3 ( T = 140°C, 48 h) in the presence of acetic acid (pH 4). The average particle length is 7.4 ± 21.3 μm, the average width is 2–15 μm, and the average thickness is 600–900 nm. The IR spectra and thermal stability of NH ...
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.
