This application provides a radar system and a terminal device. The radar system includes a controller and at least two radar modules directly or indirectly connected to the controller. The at least two radar modules include a first radar module and a second radar module, and the first radar module and the second radar module implement time division multiplexing of the controller in digital domain. Compared with an existing radar system, the radar system in this application can provide more transmit channels, more receive channels, and a larger antenna array size when the two radar systems include a same quantity of controllers. In this way, a maximum detection distance, an unambiguous angle range, and angular resolution can be increased, flexible arrangement of an antenna array and optimization of a signal processing system solution are made possible, and cabling complexity and an insertion loss that are of a feeder connecting an antenna to the radar module are reduced, so that performance of the radar system is improved, and a size, power consumption, and costs of the system are reduced.
