Abstract

The invention relates to a novel stepping frequency source for an RF frontend, and an output method thereof. The novel steeping frequency source mainly settles technical problems of low upper-limit frequency and inconvenient debugging of an output signal in prior art. The technical problems are settled through a technical solution which is characterized in that the stepping frequency source comprises a PLL circuit module, a control circuit module and a voltage stabilizing circuit module; the control circuit module is connected with the PLL circuit module; and the voltage stabilizing module isconnected with the PLL circuit module and the control circuit module. The stepping frequency source and the use method thereof can be applied to an automotive crashproof radar system.

Description

technical field [0001] The invention relates to the field of anti-collision radar radio frequency technology, in particular to a step frequency source system used for anti-collision radar radio frequency front-end and its application method. Background technique [0002] The parameters of the frequency source in the anti-collision radar system directly affect the reliability of the radar and the performance of ranging and speed measurement, so the frequency source has also become an important part of the design of the entire automotive anti-collision radar system. [0003] At present, the commonly used technologies for implementing frequency sources are mainly based on Direct Digital Synthesis (DDS) technology and the combination of DDS and PLL. Although this combination method can overcome the shortcomings of nonlinearity in the voltage modulation VCO scheme, and the frequency conversion of DDS technology is fast and the frequency resolution is high, but due to the limitati...
