Scalable cascading radar system

A scalable cascading automotive radar system comprising:

• a plurality of transceivers each capable of outputting a respective local oscillator (LO) signal;
• a combiner configured to merge the respective LO signal that is output from at least two of the plurality of transceivers into a common oscillator signal;
• a divider configured to distribute the common oscillator signal to each of the plurality of transceivers when the transceivers are emitting radar signals for detecting radar reflections from targets outside an automobile;
• and
• a radar control component configured to output information about the radar reflections from the targets outside the automobile.

A method comprising:

• obtaining, from each of at least two transceivers of a scalable cascading automotive radar system, a respective local oscillator (LO) signal;
• generating, based on a combination of the respective LO signals output from the at least two transceivers, a common oscillator signal for input to the at least two transceivers when the at least two transceivers are emitting radar signals for detecting radar reflections from targets outside an automobile;
• and
• inputting the common oscillator signal into a respective LO signal input of each of the at least two transceivers when the at least two transceivers are emitting the radar signals for detecting the radar reflections from the targets outside the automobile.
