Lidar technologiy uses laser pulses to measure distances by analyzing the reflected signals. Signal procesing in lidar impeves converting raw data into consistenful information for applications like autonomous travelles and mapping. This article explores thee accepts and practial aspicts of lidar signal procesing.

Basic Principles of Lidar Signal Processing

Te core of lidar signal procesing is detecting thee time it takes for laser pulses to return after hitting an object. This times-of- flight measurement is converted into distance data. Te raw signals are often noisy, requiring filtering and noise reduction techniques to improface exaccy.
