Abstract

One of the main requirements for radio engineering systems is their ability to withstand high levels of noise in complex, changing and a priori unknown noise environments. Improving the noise immunity of radar systems and the means of radio electronic warfare requires the development of effective noise protection systems with high information content that can operate in the presence of complex, heterogeneous interference. To identify a range-resolution element affected by non-synchronous pulsed noise, an algorithm for detecting pulsed noise has been developed. The algorithm can function effectively in conditions involving an additive mixture of uncorrelated and powerful, discrete in range correlated noise in the presence of restrictions on the dynamic range of the receiving path of the radar system. A structural diagram of a pulsed noise detector has been developed, which additionally includes a block for determining this noise at the output of a single-shot system of over-periodic compensation. To confirm the performance of the developed detector of non-synchronous pulsed interference in the conditions of an additive mixture of uncorrelated and discrete-range correlated Gaussian interference, a simulation model was developed in the Matlab&Simulink software package. The study confirmed the performance of the developed algorithm within the constraints of the dynamic range, and determined the parameters of the additive mixture of pulsed, uncorrelated and correlated interference for which the efficiency of the proposed detector exceeds that of existing detectors. The results obtained can be used to design of coherent-pulsed radar systems for detecting signals from moving targets in complex interference environments.
