Abstract
A light detection and ranging (LIDAR) system including a processor to receive a return signal from a target based on an optical beam transmitted towards the target and receive a baseband signal in a time domain based on the return signal. The processor of the LIDAR system further to produce a comparison of signal peaks of the baseband signal with an estimate of LIDAR system noise in the frequency domain, and identify targets based on the comparison.
Claims20
A light detection and ranging (LIDAR) system, comprising:
- a processor;
- and
- a memory to store instructions that, when executed by the processor, cause the LIDAR system to:
- receive a return signal from a target based on an optical beam transmitted towards the target;
- receive a baseband signal in a time domain based on the return signal;
- produce a comparison of signal peaks of the baseband signal with an estimate of LIDAR system noise in the frequency domain;
- and
- identify targets based on the comparison.
A non-transitory computer-readable medium containing instructions that, when executed by a processor in a light detection and ranging (LIDAR) system, causes the LIDAR system to:
- receive a return signal from a target based on an optical beam transmitted towards the target;
- receive a baseband signal in a time domain based on the return signal;
- produce a comparison of signal peaks of the baseband signal with an estimate of LIDAR system noise in the frequency domain;
- and
- identify targets based on the comparison.
