Abstract
A radar system and a terminal device are provided. 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 a 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.
Claims30
A radar system, comprising:
- a controller;
- and
- a first radar Rx module and a second radar Rx module connected to the controller;
- the controller processes a first digital radar signal from the first radar Rx module or a second digital radar signal from the second radar Rx module;
- the first radar Rx module and the second radar Rx module communicate with the controller in a time division manner in a digital domain;
- and
- when the first digital radar signal from the first radar Rx module is selected for processing, the second radar Rx module is put into a high impedance state, and when the second digital radar signal from the second radar Rx module is selected for processing, the first radar Rx module is put into the high impedance state.
A terminal device, comprising:
- a controller;
- and
- a first radar Rx module and a second radar Rx module connected to the controller;
- the controller processing a first digital radar signal from the first radar Rx module or a second digital radar signal from the second radar Rx module;
- the first radar Rx module and the second radar Rx module communicate with the controller in a time division manner in a digital domain;
- and
- when the first digital radar signal from the first radar Rx module is selected for processing, the second radar Rx module is put into a high impedance state, and when the second digital radar signal from the second radar Rx module is selected for processing, the first radar Rx module is put into the high impedance state.
