Abstract
Compared with the traditional analog phased array radar, the transceiver channel of the digital radar antenna array has developed from an analog component to a digital TR component, and the echo data of the array has changed from an analog signal to a digitally processed optical fiber signal. The traditional frontal test system with vector network analyzer as the core can no longer meet the frontal test requirements of digital radar. In order to solve the antenna test problem of digital array radar, this paper designs a multi-channel information processing device, which can realize the reception and processing of up to 72 channels of high-speed optical fiber data. In this paper, the hardware composition and software function of the equipment are analyzed, the theoretical derivation of digital beamforming technology is given, and the functions of digital beamforming algorithm implementation, the original data extraction, BIT information extraction, and data network transmission in software design are analyzed. Finally, the article gives a conclusion on the application effect.
