Multi-beam dwell adaptive scheduling algorithm for helicopter-borne radar

摘要

Multifunction and intelligentization are the development tendencies of the helicopter-borne radar. Based on aperture partition, two-dimensional millimeter-wave phased array radar can perform several independent agile beams and executes multiple functions, such as searching, tracking, communication, terrain-following, EMI and weapons guide, simultaneously. Depend on the characteristics of the multiple sub-array radar, a dwell scheduling algorithm is proposed which changes radar work model according to distances of targets and a relevant dwell task model is built. It is verified that the algorithm which possesses adaptive performance is able to reduce task drop ratio and improve execution capacity effectively.
