Functional Analysis of Amplitude and Phase Adjustment Units of Ground Wave OTH-Radar

Amplitude and phase adjustment units are important parts in ground wave OTH-radar transmitter, implementing conversion and adjustment of HF detection signal. This article deduces the mathematical model of amplitude and phase adjustment control device and introduces the structure and signal flow chart of amplitude and phase adjustment unit. On the basis, the operating principle of amplitude and phase control system is explained. Combined with functional analysis of amplitude and phase adjustment process, Protel99SE software was used to simulate breadboard design. Project implementation bases on the microprocessor of control and processing unit. In circuit design, the control and conversion circuits take the priority part, while amplitude and phase adjustment circuits take the assistant part. Finally, performance parameters of important component are introduced.
