Recently, laser radar as a sensor to measure distance with a forward car is widely studied. The laser radar has a characteristic that the received signal becomes to be buried in noise with increasing distance. It is difficult to measure long distance with low laser power. Then, a new type of the chaos laser radar has been studied. This laser radar is relatively resistant to noise and can simply process because of using only add calculation. However, a distance resolution of the chaos laser radar is limited by clock cycle of FPGA which is used for signal processing of the laser radar. Therefore, a new method to improve a distance resolution by a phase delay circuit is developed. As a result, the distance resolution of chaos laser radar is improved to 1/10 using phase delay circuit.
