To reach the largest detection range when detecting hypersonic targets with phased array radar， a search parameter optimization strategy is implemented based on the enhanced alert-confirm detection method. Firstly， the needs for search parameters optimization are highlighted in light of target characteristics and principles of radar. The fundamentals of alert-confirm detection are examined， and the calculation method for frame time of the mean appearance rate of new target in the search volum is given. Secondly， the dwell time， false alarm probability of alert detection and confirm detection for each position are taken as optimization variables， and the objective function is the farthest detection range. Following this， the procedures for the solution are provided. Finally， simulation is employed to confirm the viability of the proposed approach. The simulation results demonstrate that the proposed technique may achieve a greater detection range with a shorter frame time under the twin limitations of the total false alarm probability and the maximum dwell time permitted for each position. When the tracking load is the same， the proposed technique performs better than the uniform search method and the alert-confirm detection method.
