The invention belongs to the target range exterior ballistic parameter test field, and specifically relates to a burst firing bullet signal identification method for an indoor target channel light screen velocity measurement apparatus. The burst firing bullet signal identification method is used for exterior ballistic parameter measurement, and solves the velocity measurement problem under burst firing of an indoor target channel, and can quickly and accurately identify the bullet signal through burst firing. The method comprises the specific steps: 1) collecting the target crossing signals for the bullets through burst firing by a data collection card; 2) performing sliding average filtering on the signals, filtering the burr interference caused by noise; 3) according to the time width and amplitude of the signals, identifying the bullet-shaped signals satisfying the conditions and included interference signals; 4) through velocity filtering, searching the bullet-shaped signals within the limited range of velocity, and filtering the surrounding interference signals; 5) through limitation of burst firing radio frequency restriction, searching the next burst firing bullet-shaped signal adjacent to the same channel, and filtering the surrounding interference signals; and 6) through appointment of the burst firing time, searching the bullet-shaped signal of the next bullet of the other channel, and filtering the surrounding interference signals.
