In the developed technology for processing radar signals, two stages are distinguished: intra-review and multi-review signal processing based on the spectral-semantic and spatial-semantic processing models. The effectiveness of surveillance radars in the detection and recognition of subtle and sedentary air objects is enhanced by the accumulation of energy and semantic components of signal information using the mathematical apparatus of the algebra of finite predicates. It is shown how this approach can be used to detect and recognize aircraft with low Doppler resolution, which can be both in flight mode and in hover mode. Such signaling information is accompanied by various semantic distinguishing features: a sign of a trace trace and a sign of signal repetition.  Product Description popup.authors Dokhov Oleksandr I.
