A new approach to design an ultra-wideband jammer of radio-controlled explosive devices, in which a multichannel processing unit based on a set of narrowband radio-signal receiving channels with the introduction of noise interference into each channel is replaced by a single-channel microwave-photonics analogue using an optoelectronic radio-signal processor based on an optical recirculation circuit to suppress the channel of the firing code transmission, is proposed and preliminarily investigated. The layout and results of computer simulation for the proposed optoelectronic processor when transmitting standard telecommunication radio signals that confirm the possibility and determine the basic conditions for blocking a radio channel, are highlighted.

Radio Navigation System

The article considers the process of developing a local positioning system using an ultra-wideband radio signal system and its integration with a strapdown inertial navigation system (SINS). A system based on Ultra-Wide Band (UWB) technology is used as a radio navigation system. An overview of the developed experimental integrated navigation system model is presented. Algorithms for calculating the position using the propagation time of the radio signal are used to obtain a navigation solution. An analysis of the accuracy of Single-Sided Two-Way Ranging and Double-Sided Two-Way Ranging algorithms using a UWB radio module is presented. The modeling errors of the inertial navigation system were performed. The maximum permissible parameters of the sensitive element errors were obtained for integration with the radio navigation system. The scheme of integration of the navigation solution of the UWB and SINS systems is determined.
