DEVELOPMENT OF PROPOSALS FOR THE CONSTRUCTION OF FREQUENCY (PHASE) DETECTORS WITH SINGLE-CHANNEL AMPLITUDE MODULATORS OF VARIOUS TYPES AND A SHIFT GENERATOR FOR COHERENT DOPPLER RADAR OF A SHIP

Abstract

The aim of the article is to develop proposals for the construction of frequency (phase) detectors with single-channel amplitude modulators of different types and a shift generator for coherent Doppler radars for the system of ensuring navigation safety in modern shipping conditions. The problem of ensuring navigation safety is an urgent and complex task requiring a complex approach. The solution of this problem is of great importance for the efficient operation of maritime transport, which is an integral part of the country's economy. It is especially important to emphasise that this problem includes various measures - regulatory, organisational, technical, and technological. An important part of solving the problem of safety of navigation and efficient navigation is the use of technical means of navigation. These aids play a critical role both on board ships and within the shore infrastructure. They provide organisation and control of vessel traffic, which is necessary to ensure safe navigation at sea. Due to the relevance of this problem, research is being carried out to develop new ship navigation aids and improve the performance of existing ones. Currently used coastal pulse radar stations are not efficient enough to distinguish fast moving marine objects from stationary ones. In this context the development of new technical means of ship navigation based on Doppler radar systems acquires special urgency. Thus, this scientific article investigates the problem of navigation safety and the role of technical means of ship navigation in its solution. It also highlights the directions of research aimed at improving the existing systems and developing new ones to ensure the reliability of navigation and safety of maritime transport.
