Analysis of interference-protected operating modes of modern military VHF radio stations of the tactical link of management and practical recommendations of recommendations.

Abstract

At present, the Armed Forces of Ukraine have organized and operate VHF radio networks, built mainly using equipment “Motorola”, “Harris”, “Aselsan”. The main problem with the use of “Motorola” communications is the operation at fixed frequencies, in a fairly narrow frequency range (136 - 174 MHz), which leads to low noise immunity of radio lines. Unlike Motorola equipment, “Harris” and “Aselsan” radios implement modern noise-tolerant modes, including with frequency hopping spectrum spreading (FHSS).The experience of combat operations in the area of the Operation Joint Forces (OJF) indicates the need to increase the efficiency of the use of the existing VHF capabilities of tactical radio stations. In the conditions of active radio-electronic counteraction of the enemy, the increase of noise protection of radio communication lines becomes especially relevant and requires constant improvement of radio communication means on the basis of the achievements of modern science.The study, on the example of VHF radio tactical control unit “Harris” RF-7850M-HH, analyzed the current noise-protected modes of operation and developed practical recommendations for their use in the face of major types of intentional interference.The practical recommendations set out in the article can be used in the development of instructions for ensuring the operation of VHF radio stations of the tactical management in the conditions of radio interference.
