The paper, an edited and shortened version of the original, discusses a new approach to the display of collision threat parameter areas, obtained as a result of theoretical considerations. It can be applied to radar-computer anti-collision systems as well as manual radar plots.With the development of digital techniques, and electronic digital computers in particular, radar-computer anti-collision systems are now aboard ships. Digital processing of signals and data in such systems can be divided into three stages as follows:(a) Primary processing, which includes an analysis of radar signals within one rotation of the radar antenna. A result of this processing would be the position coordinates of detected objects. For relatively simple algorithms and high speed of analysis, special devices are usually employed.(b) A secondary processing, which includes a correlation of the information obtained in the primary processing stage; the objects' position coordinates in consecutive antenna rotations; and an estimate of position, motion and approach parameters. For secondary processing devices general-purpose mini- and microcomputers are usually applied.(c) A graphical display of the calculation.

The  article  describes  the  hardware‑software  complex  (HSC)  based  on  the  debugging  stand,  its  composition,  modules  and  operations. A method for synthesizing the output signal is described, a formula and a table of parameters for its calculation are  given. Signals and spectra at the input and output of the developed HSC are shown. The obtained parameters of the performance  of various agribusiness, based on the signal processor with a General‑purpose processor and two variants with General‑purpose  processors.  The  proposed  version  of  the  HSC2–3  times  wins  in  performance  compared  to  the  HSC  based  on  the  general‑ purpose processor of Intel. This is achieved through the use of modern methods and programming tools, digital signal processing  modules, as well as the optimization of the executable code. Recommendations for possible further improvement of the proposed  complex are given, which is possible due to the use of modern FPGAs and high‑speed interface.

SummaryBrain-computer interfaces (BCIs) can restore communication to people who have lost the ability to move or speak. To date, a major focus of BCI research has been on restoring gross motor skills, such as reaching and grasping1–5 or point-and-click typing with a 2D computer cursor6,7. However, rapid sequences of highly dexterous behaviors, such as handwriting or touch typing, might enable faster communication rates. Here, we demonstrate an intracortical BCI that can decode imagined handwriting movements from neural activity in motor cortex and translate it to text in real-time, using a novel recurrent neural network decoding approach. With this BCI, our study participant (whose hand was paralyzed) achieved typing speeds that exceed those of any other BCI yet reported: 90 characters per minute at >99% accuracy with a general-purpose autocorrect. These speeds are comparable to able-bodied smartphone typing speeds in our participant’s age group (115 characters per minute)8 and significantly close the gap between BCI-enabled typing and able-bodied typing rates. Finally, new theoretical considerations explain why temporally complex movements, such as handwriting, may be fundamentally easier to decode than point-to-point movements. Our results open a new approach for BCIs and demonstrate the feasibility of accurately decoding rapid, dexterous movements years after paralysis.
