In order to meet the requirements of efficient and fast evaluation of air intelligence radar detection performance in different mission environments, an air intelligence radar detection performance analysis and evaluation system is designed. The system is composed of data acquisition hardware and performance evaluation software. The hardware is responsible for collecting and storing multi-source data such as target detection data, equipment working data, ADS-B data and regional atmospheric environment data, while the software is responsible for multi-source data management and data fusion processing such as space-time unification, track interpolation, target association and error analysis. Through the system operation and example analysis, the results show that the system is easy to operate and implement, and can complete the objective quantification and analysis evaluation of air intelligence radar detection performance.
