In this paper. an antenna array aperture resource management scheme of opportunistic array radar (OAR) based on chance-constraint programming (CCP) is proposed for multiple target tracking (MTT). In the multi-target tracking scenario. multiple beams need to be synthesized to illuminate the targets. https://www.roneverhart.com/PG201004AV-Air-Compressor-Tank-Bushing-2-X-1-4-Campbell-Hausfeld/
