Description

technical field [0001] The invention relates to the technical field of detection of millimeter proximity fuzes, in particular to a radio frequency front-end circuit of a detection component. Background technique [0002] The RF front-end circuit of the detection component affects the detection performance of the proximity fuze to a certain extent. The existing detection component front-end circuit generally adopts a single detection signal input, so the detection component does not have the ability to detect 360° around. In addition, the frequency modulation signal of the modulation circuit is single. This makes the anti-interference ability of the detection component poor and cannot meet actual needs. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, to provide a radio frequency front-end circuit of the detection component, to realize the detection capability of the front-end system of the detection c...
