  2. In this paper ， an optimal search strategy by dividing the whole surveillance area into regions is presented so that the optimal search can be adaptively implemented in phased array radar. firstly ， the inherent relationship among average discovering time ， radar resources consumption ， search frame period and target distribution density is studied. secondly ， parameters for the region search are optimized to achieve the optimal search performance inside regions. then ， the optimal search frame period for each region is derived to minimize the average discovering time of targets ， where the constraint of radar time resource and the importance of each region are taken into account. finally ， the adaptability of this search strategy is discussed. only if the optimal parameters for each region are utilized and the beams are scheduled according to the optimal frame period under the radar time constraint ， the optimal distribution and the optimal scanning sequence of beams can be implemented adaptively. thus ， optimal search is adaptively implemented in the whole surveillance area

    本文提出一種分區搜索演算法，實現了相控陣雷達的自適應最優搜索.首先，研究了各區域平均發現一個目標消耗的雷達資源和目標被發現的平均時間同搜索幀周期以及目標強度的關系；然後，研究了在各區域採用兩步搜索演算法的最優參數設計，實現了局部區域的最優搜索；其次，在雷達時間資源有限和區域重要性加權的約束條件下，導出了使目標被發現的平均時間最小的區域最優幀周期；最後，討論了分區搜索演算法的自適應性.只要採用各區域的最優參數，按最優幀周期調度雷達波束，就可以自適應地實現使目標被發現的平均時間最短的波束的最優分佈和掃描順序，即自適應最優搜索
  3. This paper proposes principle and method of optimizing energy and time distribution in elevation to obtain good performance in the frame time, and this method has been used in engineering project of several phased array radars

    文中提出了仰角掃描能量時間的優化分配原則和方法，使雷達的能量和時間在幀時間內分配達到性能最佳，這種方法已在多部相控陣雷達設計中採用。
