Abstract: A signal processing method includes: obtaining a first detection signal corresponding to a first detection region, where the first detection signal includes a noise signal of the first detection region; and outputting indication information based on the first detection signal, where the indication information indicates that interference exists in the first detection region. According to the method, a proactive alarm function is implemented. The indication information indicates interference such that an alarm can be reported in time when interference occurs.

Abstract: A lidar may include a control module, a laser, and a detector. The control module is configured to determine N first sequences and N groups of first time intervals, where N is an integer greater than or equal to 1. The laser is configured to emit N first laser signals based on the N first sequences and the N groups of first time intervals. The detector is configured to receive N second laser signals, and convert the N second laser signals into electrical signals to obtain N first electrical signals. The control module is further configured to determine N second sequences and N groups of second time intervals based on the N first electrical signals.
