Research results

As a result of the implementation of scientific and technical work under the state order (Contract No. DZ-40), design documentation was developed for a pilot plant for the production of biofuel in the utilization of biogenic waste, and an operating pilot plant was manufactured. The installation implements a technology developed and tested by laboratory specialists.

By order of the Institute of High Technologies of the Academy of Sciences of Heilongjiang Province (Harbin, China), an experimental sample of an installation for producing alternative biofuels from biogenic waste (sludge, food waste, etc.) was manufactured and handed over to the customer, where it successfully passed acceptance tests.

Research results obtained:

2. Predicate models of process knowledge about inconspicuous airborne objects based on the use of the mathematical algebraic apparatus of finite predicates are proposed; they are suitable for use in intelligent radar systems when creating automatic systems for detecting and recognizing the marks of signals from inconspicuous aircraft and other airborne objects. The developed models take into account the dynamics of the interperiodic configurations of the primary patterns of the signal environment, formed by a set of radar signals received during the operation of the radar. These initial pictures contain objective information about airborne objects. On the basis of radar marks, symbolic predicate models of images of air objects are formed, which serve as the basis for creating a virtual space of process knowledge of inter-period processing of signal information in surveillance radars. The symbolic model makes it possible, on the basis of information about the behavior of the signal in each analyzed processing element and predicates of events (features), to distinguish the processing element from the object and the interference not by exceeding the threshold, but as a result of the analysis of qualification features, which is most effective in identifying weak reflected signals. from subtle objects.
3. The developed processing methods based on the predicate model of process knowledge make it possible to automate the processes of detecting and recognizing subtle air objects and making decisions.
4. The developed algorithms and programs of an intelligent automated system for detecting and recognizing subtle air objects of observation radars look like a hierarchical structure in a digital predicative form:

• the first level of the processing algorithm is the presentation of the data obtained as a result of observations in an easy-to-use form;
• the second level is a description of unary and binary connections between data, which determine the mechanism for transforming input data in the form of a matrix of numbers into a matrix of knowledge, taking into account predicate information about relationships (connections) between input data;
• the third level – the accumulation of knowledge based on data and information about the relationships between them is presented as obtaining new networks of relationships in the form of predicate features;
• the fourth level of meta-knowledge unites all previous levels, allowing you to make decisions about the detection and recognition of radar marks. Algorithmically, the level of meta-knowledge has the form of a predicate operation that connects all the information received and in the process of processing it receives the final decision.

Programs have been developed that implement hierarchical algorithms for the developed automated process knowledge processing system for identifying and recognizing low-mobility air objects in observation radars.

New information technologies for signal processing are developed on the basis of both inter- and multi-view signal processing operations, taking into account the capabilities of the developed: predicate models of process knowledge, methods of processing process knowledge using the algebra of finite predicates, a decision-making method based on known precedents.
