Abstract

The invention relates to a radar signal wavelength division multiplexing module design method based on a VPX platform. The method comprises steps: multiple digital signals generated by a phase array radar are received, multiple coarse wavelength division single-mode optical signals are outputted through an electric light conversion circuit, electromagnetic interference and crosstalk between channels are inhibited through a shielding module, a single-channel coarse wavelength division multiplexing optical signal is formed through a combiner, is transferred through an optical slip ring and enters a signal processing cabinet, the single-channel multiplexing optical signal is converted into multiple single-mode optical signals with different wavelengths through a wave separator first, then the optical powder is raised through a relay and an amplification circuit, multiple CML level signals are outputted through a photovoltaic conversion circuit and transmitted to a signal processing module, and therefore miniaturization and light-weight application of the wavelength division multiplexing function can be achieved on a VPX general information processing platform.

Description

technical field [0001] This method uses wavelength division multiplexing technology to design a wavelength division multiplexing module based on the VPX platform architecture according to the reliability requirements of the data transmission link of the radar rotating part under research. It can reduce the volume of the radar antenna integrated control subsystem and information processing subsystem, and help improve the stability of the data transmission link of the radar rotating parts, which has considerable application value. Background technique [0002] Due to the continuous increase of the data transmission volume of modern digital array radar optical fiber, single-channel optical fiber often cannot meet the actual data transmission requirements. The application of multi-channel optical fiber puts forward higher requirements for the data transmission link of radar rotating parts. The application of the multi-channel optical fiber data transmission problem is solved, bu...
