Phase correction based on baseband delay

A radar device, comprising:

• a first receive (RX) channel comprising a first analog baseband processing component;
• a second RX channel comprising a second analog baseband processing component;
• one or more components to:
• provide, during a first time window, a reference signal at a first node in the first analog baseband processing component;
• provide, during the first time window, the reference signal at a second node in the second RX channel;
• and
• determine a first baseband delay associated with the first analog baseband processing component based on a difference between a phase of the reference signal at an output of the first RX channel and a phase of the reference signal at an output of the second RX channel.

A method, comprising:

• providing, during a first time window, a reference signal at a first node in a first analog baseband processing component of a first receive (RX) channel of a radar device;
• providing, during the first time window, the reference signal at a second node in a second RX channel of the radar device, the second RX channel including a second analog baseband processing component;
• determining a first baseband delay associated with the first analog baseband processing component based on a difference between a phase of the reference signal at an output of the first RX channel and a phase of the reference signal at an output of the second RX channel;
• determining a first phase response of the first analog baseband processing component based on the first baseband delay;
• and
• correcting a digitized output signal of the first RX channel based on the first phase response to create a phase corrected output signal associated with the first RX channel.
