Research on the Signal-to-Noise Ratio in Sliding Spotlight Mode Down-Looking Synthetic Aperture Imaging Ladar
Under far field simulated conditions by using collimator with 15 m focal 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.
