A new signal generation method for phase laser ranging finder is proposed based on direct digital synthesizer technology of FPG A. We present the design of hardware and software of the system. The results of experiments proved that the SNR is more than 60dB. Compared with other technologies,it has higher stable frequency,frequency switch rate and lower power consume.
