Chapter 2: General principles of constructing radio electronic systems of marine objects

The theory underlying the design of radio electronic systems carried on marine objects was elaborated. A distinction was made at the outset between active, semiactive, and passive automatic control systems, depending on the nature and location of the physical field of interest (such as sound). Simplified block diagrams of the various systems are given and explained. The effect of interferences is covered. A mathematical discussion of the various types of signals in systems of local action and oscillation carriers is also presented.
