Abstract: A sending apparatus, detection system, and detection method of a lidar are configured to exclude a false target from a plurality of targets. Frequency-sweep optical signals with different slopes are introduced, the frequency-sweep slopes of the different frequency-sweep optical signals are opposite in sign in a time period, and absolute values of the frequency-sweep slopes are not equal. For a plurality of real targets, coherent detection is performed in at least two time periods separately corresponding to the different frequency-sweep optical signals.
