The radar task scheduling problem of phased-array radar (PAR) in detecting hypersonic-glide vehicle (HGV) targets has been studied. Based on the hypersonic-glide vehicle motion-model and detection model. a two-stage scheduling strategy was designed. Task scheduling is divided into two stages: prescheduling and formal scheduling. https://fitnessgravesyardes.shop/product-category/electronic-display-board/
