Abstract
For the problem of weak signal detection in range measuring laser radar, a new method using m-sequence is proposed in this paper. The scheme of the radar signal process system based on high speed DSP is presented also. Using the excellent correlation property of m-sequence, correlative detection and accumulation algorithms, this method can effectively improve the performance of the laser radar. A technique named 3-point interpolation is proposed to enhance the range accuracy further. Finally, experimental results are provided to show validity of the method.
