Abstract
A radar system may include a set of analog components to perform one or more radio frequency (RF) operations during an active radar phase of the radar system. The radar system may include a set of digital components to perform one or more digital processing operations during at least a digital processing phase of the radar system. The one or more digital processing operations may be performed such that performance of the one or more digital processing operations does not overlap performance of a substantive portion of the one or more RF operations.
Claims21
A radar system, comprising:
- a set of analog components to perform one or more radio frequency (RF) operations during an active radar phase of the radar system;
- and
- a set of digital components to perform one or more digital processing operations during at least a digital processing phase of the radar system,
- wherein the one or more digital processing operations are performed such that performance of the one or more digital processing operations does not overlap performance of a substantive portion of the one or more RF operations,
- wherein the set of analog components is supplied by a first power supply, associated with a first noise power, during performance of the one or more RF operations, and
- wherein the set of digital components is supplied by a second power supply, associated with a second noise power higher than the first noise power, during performance of the digital processing operations.
A radar system, comprising:
- a set of analog components to perform one or more radio frequency (RF) operations during operation of the radar system,
- wherein power to the set of analog components is supplied by a first power supply during performance of the one or more RF operations,
- wherein a second power supply of the radar system is deactivated during
- the performance of the one or more RF operations;
- and
- a set of digital components to perform one or more digital processing operations during the operation of the radar system,
- wherein power to the set of digital components is supplied by the second power supply during performance of the one or more digital processing operations,
- wherein a noise power of the second power supply is higher than a noise power of the first power supply.
A method, comprising:
- storing, by a radar system and based on sampling a radar signal, first data in a first memory component of a plurality of memory components of the radar system,
- wherein the first memory component is operating in an active power state during the storing of the first data in the first memory component, and
- wherein a second memory component, of the plurality of memory components, is operating in a low power state during the storing of the first data in the first memory component;
- and
- storing, by the radar system and based on sampling the radar signal, second data in the second memory component,
- wherein the second memory component is in the active power state during the storing of the second data in the second memory component, and
- wherein the first memory component is in the low power state during the storing of the second data in the second memory component.
