단원형배열안테나의 합차 모노펄스 주엽 식별 = Main-Lobe Recognition for Sum-Delta Monopulse of Single-Ring Circular Array Antenna

다국어 초록 (Multilingual Abstract)

The target must be located within the main-lobe of the antenna in order to measure the direction of the target by using sum-delta monopulse technique. The most common way if the target is located within the main-lobe is to compare the amplitude of the sum channel received signal with the delta channel received signal. However, in the case of the single-ring circular array antenna, it is difficult to apply the conventional method due to its structural limitation where antenna elements do not exist in the center of the array. In this paper, we proposed a novel method to identify whether a target is located within the main-lobe by appropriately adjusting the feeding amplitude of each element constituting the single-ring circular array antenna through the particle swarm optimization method.
Simulation results showed that the proposed method can determine whether the target is located within the main-lobe of the single-ring circular array antenna.
