Radar data processing system with automatic tracking capability composed of search radar and electronic computer is one of the development directions of modern radar technology. Based on the theory and application of a series of performance problems related to radar data processing system, this paper based on the statistical characteristics of the tracking process, using the concept of the initial detection probability given by the track to derive a specific radar data processing system for a specific target Tracking probability and its calculation formula. Through computer simulation, various factors influencing system performance are statistically analyzed and calculated with parameters, and some new understandings and results are obtained. It is of some value for such issues as determining target classifications, analyzing the applicability of tracking algorithms, and determining the reaction time of the system.
