With the rapid development of my country's national economy and the continuous increase of domestic and foreign trade volume, maritime transportation has become more prosperous. Radar signal processing technology is the core technology for marine radar to detect maritime targets, and plays a vital role in safe and efficient maritime transportation. The purpose of this paper is to study the construction of distributed radar signal processing system, introduce the basic structure, signal model and flow signal processing algorithm of distributed radar system, analyze the influence of time delay and amplitude phase error. This paper introduces the traditional node width and phase error correction methods for distributed radar systems, and analyzes the algorithm for the two situations of intra-node and inter-node, and analyzes the effectiveness of the algorithm. Verified by simulation experiments. Finally, the results of the radar wave signal processing ability are compared and tested, and the results show that the signal processing integrity rate of the traditional system is lower than 90%. The signal processing integrity rate of the system constructed in this paper is close to 100%, so the distributed marine radar signal processing system constructed in this paper is obviously better than the traditional radar signal processing system.
