Title: Method of obtaining a three-dimensional image in a side-scan radar with synthesizing an antenna aperture
Inventor: Velikanova Elena Pavlovna
IPC: G01S13/90
Filed: 2019-04-30
Granted: 2019-12-19
Abstract: FIELD: radar ranging and radio navigation. 
     SUBSTANCE: invention relates to radio vision systems and can be used to produce a three-dimensional radar image of scene objects with a lateral view with high resolution both in range and angle of azimuth, regardless of weather conditions and level of illumination. High range resolution is ensured by using broadband signals with linear-frequency modulation. High azimuth resolution is obtained by synthesizing the antenna aperture during movement of the radar when observing the scene objects for a long time from different perspectives. Elevation of objects is assessed by frequency scanning with a beam in a vertical plane, which ultimately enables to build a three-dimensional radar image. Platform of the radar is ground transport or low-flyer unmanned aerial vehicles. Objects of the scene are surrounding objects (sidewalks, bushes, trees, people, buildings, other vehicles, etc.). Technical result is achieved by combining partial signals obtained at different positions of the FP antenna as frequency scanning of the beam and addition to the flat image of the azimuth-range of the additional axis along height. 
     EFFECT: high information value of the radar image owing to additional extraction of information on the altitude profile of surrounding objects.

Abstract: FIELD: electrochemical processing. 
     SUBSTANCE: invention relates to the field of electrochemical processing of complex-shaped surfaces at ultra-small interelectrode spaces (IES). The method includes shaping the shaped surfaces of the part by continuous pulse-cyclic electrochemical processing with an oscillating electrode-tool during its working supply in the direction of the part with a control measurement of the IES, during which, when the electrode-tool reaches the specified minimum IES, the process current is stopped, while further supply is continued de-energized tool electrode towards the workpiece. The control measurement of the IES is carried out in each working cycle. In case of touching the part with a de-energized electrode-tool during the control measurement of the IES, the working feed is slowed down or stopped without interrupting the pulse-cyclic process of electrochemical processing and the working feed is resumed after the formation of a free IES between the electrode-tool and the part, excluding their touching. At the moment of resumption of the working feed, the relative speed of approaching the electrodes is provided, which is equal to the difference between the speed of the working feed and the rate of dissolution of the material of the part and less than the rate of dissolution of the material of the part.
