“…Certain aspects of the optimal detection of chaotic sequences due to processing gain are being investigated. In [ 46 ], the problem of restoring the chaotic map used for the chaotic PM is solved with the Kalman filter. A method for forming chaotic sequences is proposed in [ 47 ], which, according to the validation criterion of their detection in a noisy channel, should be better than Gold code.…”

A modulation method is proposed for generating identical UWB chaotic radio pulses using an analog generator of chaotic oscillations. The problem is on the edge of two contradicting requirements: (1) theoretical ability to produce a huge number of various-shape signals, because of high sensitivity to the initial conditions of the generator; (2) the necessity to reproduce oscillations of the same shape both in the receiver and in the transmitter for the implementation of coherent methods of signal processing. The considered method allows us to resolve this contradiction. A single-transistor chaotic oscillator with single power supply and frequency range 100 to 500 MHz is proposed. A mathematical model of the generator (a system of ODEs) was derived. A method of generating chaotic radio pulses with a reproducible shape that could be varied in a manner that is controlled and natural for UWB radio by means of changing the supply voltage of the chaotic oscillator is shown. The mathematical model of the generator is simulated numerically and proves the proposed ideas. The shaping and the replicability of UWB pulses was experimentally proven in an analog domain on a testbed with four instances of the chaotic generator.

Применяемый подход связан с исследованием изменения энтропии измеряемых полей, которое возникает вследствие активизации процессов разломов литосферных плит непосредственно перед землетрясением. Удалось выявить феномен процессов с высокой степенью детерминированности, возникающих перед сейсмическим событием. Зарегистроровано изменение характера движения станций космической геодезии и геодинамики КрАО по всем координатам за несколько дней до начала блока турецких землетрясений, что говорит об изменении балланса сил в регионе.
