[Abstract]:The (FSCS) laser signal source of large bandwidth linear frequency modulation step signal is synthesized by discrete laser to realize high resolution ranging. According to the principle of FSCS signal ranging, the influence of laser parameters on synthetic FSCS signal and its error tolerance are numerically calculated. The calculation results show that the error of starting frequency and time is the most important factor that leads to the deterioration of ranging resolution of synthetic FSCS signal. In addition, a linearly modulated wavelength laser with a central wavelength of 1550nm and a linewidth of 150kHz is used to simulate the synthetic FSCS signal by optical chopping and demonstrate the range finding with high resolution. Theoretical analysis and experimental results show that it is feasible to synthesize high resolution ranging FSCS signal by discrete laser.
