In this study, separate search areas are set in the threat area to maximize the operational efficiency of the multi-function radar, and a search operation method for multi-search areas according to their importance, is proposed. In particular, to satisfy the frame time required to fulfill the maximum detection range for each search area, a search ratio calculation method using the search times of each area is proposed. In addition, to satisfy the search ratio, a search operation method is proposed that can meet the requirements for multi-search areas by switching the search area based on the threshold for the search time, for each area. In this study, two search areas with different search waveforms were set, and the achievement of the requirement was mathematically verified. In addition, the suitability of the proposed method was confirmed through performance analysis under various simulation conditions.
