摘要
针对单站多目标同时测控中存在的问题,提出将数字波束形成技术应用于单站测控系统天线中,以更好实现对多目标的同时测控。针对多目标测控对天线系统的特殊要求,并结合数字波束形成技术自身的特点,分析了数字波束形成技术在实现全空域波束扫描、大型阵列波束形成和多目标跟踪时存在的3方面突出问题,并提出了解决的初步思路和方向。分析表明,采用数字波束形成技术的天线具有诸多优势,其在对多目标测控中具有广阔的发展前景。
In order to solve the problems encountered in multi-target tracking, telemetry and command （TT＆C） by a monostatic station, digital beamforming （DBF） is proposed to be used in the antenna of the monostatic station TT＆C system. Combining the demands of the antenna for multi-target TT＆C and the characteristics of DBF, problems of DBF being applied in hemispherical coverage scanning, large array beamforming, and multi-target tracking are investigated and described in detail, and some preliminary approaches are also presented. Results show that, advanced DBF technolo- gy improves the antenna^s performance and has widespread development prospects in the area of multi-target TT＆C.
