A Multi-Channel Millimeter-Wave Imaging High-Speed Data Acquisition and Transmission System Based on Optical Fiber and PCIe Interface

This paper describes a high-speed data acquisition and transmission system for millimeter-wave imaging based on optical fibre and PCIe interfaces, which includes a multi-channel analog-to-digital conversion module, a data transmission module, and a data reception module. The scheme can circumvent the inherent shortcomings of bulky volume, poor reliability, and inability of large-scale expansion of array channels caused by the multi-channel data transmission system using multi-strand SMA cables, and has the advantages of small volume, light weight, fast data transmission rate, and easy to upgrade the performance, etc. It can be widely applied to the multi-channel data acquisition and transmission system, and has a broad application prospect in the field of array imaging radar and sonar imaging.
