Abstract
A LIDAR system comprises a chaotic signal generating device, a signal transmitting device and a signal processing system sequentially coupled in series. The chaotic signal generating device is configured to generate a chaotic signal and comprises a feedback device and a laser generator configured to generate a laser signal. The feedback device is configured to receive the laser signal, generate the chaotic signal and a feedback signal according to a laser signal, and transmit the adjusted feedback signal to the laser generator. The signal transmitting device is configured to receive the chaotic signal, so as to generate a reference signal and detection signal, wherein the detection signal is transformed into a reflected signal after being reflected by an obstacle. The signal processing system is configured to receive the reference signal and the reflected signal, so as to determine a delay time by using a frequency domain phase modulation algorithm.
