| Abstract: | In this paper,according to the basic theory of switched line phase modulator,a micro-strip switched line phase modulators have been designed in the millimeter-wave radar front-end system.First we introduce the principle of the phase modulators and analysis it’s specific characteristics of the circuit.Secondly we design a actual circuit and process.Finally we test the oscillator part of the millimeter wave radar system and get some corresponding test data.These data indicate that the design of this DRO is feasible to meet the millimeter-wave radar systems. |
