In order to effectively improve the range resolution of air traffic control primary surveillance radar (PSR) detecting the arresting targets, a method of high resolution target extraction using wideband information processing technology is proposed in this paper. The critical technologies such as wideband signal detection, scattering center extraction, aircraft formation track initiation and cluster target correlation are studied emphatically, on the basis of simulation analysis, the delicate signal processing and data processing design are optimized and improved. Finally, the range resolution of PSR is tested and verified by practical application, the results show that the wideband information processing technology significantly improves the range resolution of PSR, radar is good at automatically picking up individual targets in formation flight, the performance is obviously better than similar imported equipment.
