Today, laser radar is widely studied as in-car radar. The laser radar has a characteristic that the received signal becomes to be buried in noise with increasing distance. When the long distance is measured, it needs a high power laser, or the repetitive process that uses multiplication and integration. Therefore, 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 additional process. But, the chaos laser radar has been off-line processing thus far. Then using FPGA in the signal processing, the on-line measurement system is developed. As a result, the distance up to 95m can be measured on-line.
