Study on the Frequency-Modulated Continuous-Wave LiDAR Mutual Interference

Abstract

We present mutual interference problems in the frequency-modulated continuous-wave (FMCW) LiDAR. There are two types of the mutual interference, the transient interference, and the in-band interference. We show that the former case induces degradation of signal-to-noise ratio (SNR) in measurement, and the latter case can introduce ghost images and/or objects in 3-D mapping.
