Active differential SAL data and DSAL data with vibration self-compensation

Both are SAL imaging time stream data, with each set containing three sets of trigger, channel 1, and channel 2 data. The target echo time stream data needs to be rearranged into a (fast time * slow time) matrix and compressed in the distance direction and filtered in the azimuth direction to obtain the image. Wavelength 1550nm, rotating mirror angular velocity 0.422rad/s. The target speed in DSAL is 181mm/s.
