“…Radar object signatures, the so-called "fingerprints" are encoded with a string of data representing information about the object in the form of a certain notation. Also to this signature string is added a board identifier, if it is represented by a transponder or otherwise defined by radar [15,16]. If the signature symbols are represented as ANSI codes and supplemented with obligatory on-board identifiers, then it is possible, by dividing them into ranges, to quickly and accurately analyze how many, from where and which aircraft are in the monitored space [17]…”

The paper considers an accelerated algorithm for distributing numbers over given ranges. The proposed algorithm allows you to quickly distribute integers over predetermined ranges with deterministic boundaries and calculate the number of elements in each of the ranges. If the number of ranges lies in the range from 64 to 256, then the time for solving the problem will be reduced by 9–33 times. The algorithm can be implemented in both software and hardware.

The article describes a rather efficient method for processing a signal of the MODE-S format, which has distortions in amplitude and timing parameters. Distortion can be caused by various factors, such as the presence of interference in the air and the reflection of the signal, the impact of various electromagnetic fields. Receiving and further processing of the signal with distortion can not be performed correctly using simple algorithms that do not take into account these features. The method described below allows processing part of the distorted signals correctly and increasing the total number of decoded signals. MODE-S is part of a large air traffic processing and monitoring system. Today, a large number of civil aircraft are equipped with receivers and transponders of signal in MODE-S format. This system allows identifying aircraft and obtaining the necessary information about the flight in a simple way. MODE-S works on the question-answer principle. The so-called “question” is sent to the aircraft in order to obtain specific information about the flight. The aircraft accepts this “question”, analyzes its format and, depending on it, sends an “answer” back. It is very important to process correctly as many signals as possible, because the information in them is important and must be received on time.
