摘要: 研究了相控阵雷达的系统反应时间,提出了当采用TWS和TAS两种跟踪方式时,计算相控阵雷达反应时间的公式,揭示了反应时间与搜索、跟踪和截获方式及其参数之间的关系.研究了截获参数的优化.比较了采用两种跟踪方式时的系统反应时间.实验结果说明,采用TWS跟踪方式时,反应时间主要决定于搜索帧周期和目标的速度,与目标个数无关;采用TAS跟踪方式时,反应时间主要取决于目标个数和速度,与搜索帧周期关系不大.

Abstract: The system reaction time of phased array radar is studied. The formula to compute the reaction time is proposed when TWS and TAS tracking mode are applied in phased array radar. The relationship between the reaction time and the searching, tracking and acquisition mode and their parameters are established. The optimization for the acquisition parameters is studied. The reaction times for the two tracking modes are compared. It is shown by the examples that the reaction time of TWS primly depends on the frame period of search and the target's velocity, and has nothing to do with the number of target. The reaction time of TAS mainly depends on the number and velocity of target, and is little effected by the frame period of searching.
