Abstract	Under far field simulated conditions by using collimator with 15 mfocal length,we present a sliding spotlight mode of the down-looking synthetic aperture imaging ladar(SAIL).Based a single point target echo collection equation,the signal-to-noise ratio in sliding spotlight mode is analysed.Theory and experiment confirm that the sliding spotlight mode can improve signal-to-noise ratio when we can extend the effective acquisition time length.
