High-precision high-repetition-frequency gating signal generation method for satellite laser ranging

The invention discloses a high-precision and high-repetition-frequency gating signal generation method for satellite laser ranging, and belongs to the field of laser ranging. The method specifically comprises the following steps: storing an interpolation coefficient provided by a user; recording a time value of an input ignition signal pulse relative to a system clock, and calculating a required delay duration based on an interpolation coefficient; dividing the delay duration into a coarse delay duration and a fine delay duration; calculating a coarse delay period and a fine delay duration, and storing the coarse delay period and the fine delay duration into FIFOc and FIFOx; and carrying out delay processing on the input signal to finally obtain a high-precision and high-repetition-frequency delay gating signal output pulse. The high-precision and high-repetition-frequency satellite laser ranging gating signal output circuit has high-precision, high-repetition-frequency and high-real-time-performance delay si
