Аннотация
Background. The paper considers the operation of an onboard moving target selection system (MTS) with external coherence under discontinuous passive interference. To improve the efficiency of the MTS system, a narrowband filter is used in the processing path, the output signal of which is a reference for the MTS system in the gaps of passive interference. The purpose of the work is to develop and study the means of selecting moving targets of an onboard radar under conditions of discontinuous passive interference. It is necessary to show that the output signal of a narrowband filter tuned to the frequency of passive interference retains all the statistical properties of the passive interference preceding the appearance of the gap, and can be used as a reference voltage in the MTS system. It is required to study the operation of the MTS system under discontinuous passive interference. Materials and methods. The work is based on the spectral-correlation method for analyzing the statistical properties of signals and devices for their processing. Results. An expression is obtained for the output signal of a narrowband filter detuned relative to the frequency of passive interference. It is shown that the output signal of the narrow-band filter retains all statistical properties of passive interference and can be used as a reference voltage in the MTC system with external coherence. The results of calculating the passive interference suppression coefficient and the coefficient of sub-interference visibility are presented depending on the statistical characteristics of the useful signal and passive interference. Conclusions. The proposed method for creating a reference voltage for an onboard MTC system with external coherence allows one to effectively solve the problem of detecting moving targets against the background of discontinuous passive interference. The results obtained in the article can be useful in designing onboard Doppler radars using MTC tools.
