Linearization of multi-chirp predistorted laser for FMCW lidar

Systems and methods for measurement, predistortion and linearization of FMCW (Frequency Modulated Continuous Wave) lidar chirp laser signals are disclosed in which I/Q channels of IF optical signals of a combination of delayed and undelayed versions of the laser signals are generated and used in the process of predistortion of waveform data for linearization. 本发明公开了用于FMCW(调频连续波)激光雷达啁啾激光信号的测量、预畸变和线性化的系统和方法，其中生成激光信号的延迟和未延迟版本的组合的IF光学信号的I/Q信道，并将其用于对波形数据进行预畸变的过程中以进行线性化。
