    The brief analysis of the development of L. V. Kantorovich's ideas in the works of his students and followers has been presented. This intellectual base can be used in solving the problems of digital transformation, digitalization, creation of digital platforms and their ecosystems in the digital economy. It has been proposed to create an active element of a new branch of knowledge economy – the digital economy – in the form of β€œAssociation of departments of applied mathematics of economic and managerial profiles of Russian Universities”, the advisability of this decision has been substantiated. The Association will allow you to simultaneously conduct research on a wide range of topical issues of the digital economy, optimally form creative teams and expert groups, carry out constant scientific communication in real time, and connect talented young people to research between the postgraduate students, graduate students, and students. Working together in the structure of the Association, the departments of higher education institutions will be able to show the effect of synergy and achieve much more results in their activities. The Association has a great educational potential, which can be effectively used to improve the various levels of personnel potential of management systems. Creating associations in the field of breakthrough technologies is the best way to activate Russia's intellectual potential

    The description of a new method for increasing the resolution of radio pulse sensors (RPS) designed for short- range radar systems (SRRS) for detecting and measuring motion parameters of location objects is presented. The essence of the method is that the controlled area of space with the targets located in it is periodically irradiated with probing radio pulses, and during their radiation, radio pulses reflected from the targets are simultaneously received and divided into two quadrature channels. Next, they are mixed with probing radio pulses, and the time-overlapping parts of these radio pulses are converted into the region of low Doppler frequencies in the form of two quadrature video pulses. Then, the quadrature video pulses received in these channels are sampled by amplitude, stored at multiple points in time and digitally processed according to the proposed algorithm. The method is implemented in the RPS made on the basis of a horn-lens antenna, a Doppler receiving and transmitting module with quadrature outputs of converted signals, a synchronization and pulse generation unit, as well as a digital signal processing unit. The RPS can be used in onboard (for example, automotive) SRRS designed to detect moving targets, measure the distance to them, as well as determine the speed and direction of movement. The results of experimental studies have been obtained on the example of the 8-mm autodyne RPS made on the basis of the oscillator on a planar Gann-diode.Β Bogatyrev E. V., Vishnyakov D.

The features of the formation of signals received from a distributed target in the form of an ensemble of an arbitrary number of point reflectors are considered. Calculations of signals by the proposed step method are performed for the case of two point reflectors on a location object situated at different distances from the SRRS. The distinctive properties of the signals generated when receiving the first and subsequent radiation reflected from the target are established. After sending the probing radiation, the reception of the first reflected radiation from a set of brilliant points is accompanied by the formation of a linear superposition of signals from individual reflectors. The reception of subsequent reflections causes the appearance of a combinational interaction of the signals of individual reflectors. The nature and magnitude of such interaction is determined by the magnitude of the feedback parameter of the autodyne SRRS, which depends on the values of the frequency deviation and the delay time of the reflected radiation. The results of experimental studies of the autodyne SRRS with simultaneous amplitude and LPM have been obtained using the oscillator module made on the 8-millimeter Gann diode
