相控阵雷达中的TWS和TAS跟踪技术

Track-While-Scan and Track-and Search Tracking Techniques in Phased Array Radar

本文从基本概念和综合性能预测的角度，研究了相控阵雷达中的两种跟踪技术──边扫描边跟踪和边跟踪边搜索技术．比较了在相控阵雷达中这二者的异同，以及在机械扫描雷达中利用边扫描边跟踪技术时的异同．提出了在相控阵雷达中计算二者综合性能指标的方法，包括精度、目标容量、资源利用率和反应时间，并对这两种技术的性能进行了比较．

Two tracking techniques-Track-While-Scan and Track-and Search are studied from the aspet of basic concepts and the performance prediction in this paper. The similarities and differences of these two techniques in phased array radar and of track-while-scan technique in phased array radar and mechanical scanning radar are compared. The methods to calculate the performance index of the two techniques in phased array radar are proposed, including accuracy, target capacity,utilization rate of rare and reaction time. The performance of the two techniques is compared.
