The millimeter wave (mmWave) bands and other high frequencies above 6~GHz\nhave emerged as a central component of Fifth-Generation (5G) cellular standards\nto deliver high data rates and ultra-low latency. A key challenge in these\nbands is blockage from obstacles, including the human body. In addition to the\nreduced coverage, blockage can result in highly intermittent links where the\nsignal quality varies significantly with motion of obstacles in the\nenvironment. The blockages have widespread consequences throughout the protocol\nstack including beam tracking, link adaptation, cell selection, handover and\ncongestion control. Accurately modeling these blockage dynamics is therefore\ncritical for the development and evaluation of potential mmWave systems. In\nthis work, we present a novel spatial dynamic channel sounding system based on\nphased array transmitters and receivers operating at 60 GHz. Importantly, the\nsounder can measure multiple directions rapidly at high speed to provide\ndetailed spatial dynamic measurements of complex scenarios. The system is\ndemonstrated in an indoor home-entertainment type setting with multiple moving\nblockers. Preliminary results are presented on analyzing this data with a\ndiscussion of the open issues towards developing statistical dynamic models.\n
