The development of a voltage-controlled generator with digital tuning for a multifunctional radar station

The necessity of multifunctional radar station development for solving various tasks, including environmental monitoring, is substantiated. The necessity has been established for solving several tasks, including environmental monitoring of air spaces, scanning the emitted microwave signal frequency in the range from 2 to 18 GHz, with a tuning step of 10 MHz. The emerging radar station problems during the implementation of this range are considered. The disadvantages of analog voltage-controlled generators (VCG), which are used in radar stations to synthesize a grid of microwave frequencies in the range of several GHz, are considered. A digital tuning VCG design has been developed on the domestic component base to implement the synthesis of a microwave frequency grid in the range from 2 to 18 GHz. The main characteristics of the developed VCG are investigated and compared with similar developments of the world's leading manufacturer (Planar Monolithics Industries). The effectiveness of radar station with a developed VCG usage for solving various tasks is shown.
