An anti-jamming signal transmission method

Abstract

The invention discloses an anti-interference signal transmission method, comprising the following steps: S1: a digital signal processing chip sends a transmission signal to a local oscillator of a transmitting phase-locked loop in advance through a transmission line, and the local oscillator of the transmitting phase-locked loop collects the transmitting signal through an acquisition module , to obtain a stable transmission signal, the acquisition module uses a low-pass input filter to filter out AC interference, and uses compensation measures for DC series-mode interference; S2: The preamplifier module of the acquisition module has high input impedance and high common-mode rejection Compared with the differential amplifier circuit to complete the smooth input of electrical signals and the elimination of common-mode noise, and the amplification of the transmitted signal; the acquisition module of the present invention uses a low-pass input filter to filter out AC interference, and uses compensation measures for DC series-mode interference ; The pre-amplification module of the acquisition module is a differential amplifier circuit with high input impedance and high common-mode rejection ratio to complete the smooth input of electrical signals and the elimination of common-mode noise.
