Lidar receiver with dual analog-to-digital converters

A light detection and ranging (lidar) system, comprising:

• a transmitter to transmit an optical beam;
• and
• a receiver to receive a reflection of the optical beam, the receiver comprising:
• a first frequency filter to pass a first range of frequencies of an analog signal that is based at least in part on the reflection;
• a second frequency filter to pass a second range of frequencies of the analog signal that is different from the first range of frequencies of the analog signal;
• a first analog-to-digital converter (ADC) to derive a first digital signal based on the first range of frequencies of the analog signal using a first sampling rate;
• and
• a second ADC to derive a second digital signal based on the second range of frequencies of the analog signal using a second sampling rate that is different from the first sampling rate.

A method, comprising:

• filtering, by a light detection and ranging (lidar) system, an analog signal to a first range of frequencies of the analog signal;
• filtering, by the lidar system, the analog signal to a second range of frequencies of the analog signal;
• converting, by the lidar system and using a first sampling rate, the first range of frequencies of the analog signal to a first digital signal;
• converting, by the lidar system and using a second sampling rate that is different from the first sampling rate, the second range of frequencies of the analog signal to a second digital signal;
• generating, by the lidar system and based on the first digital signal, a first digital representation associated with a first distance range;
• and
• generating, by the lidar system and based on the second digital signal, a second digital representation associated with a second distance range.
