Being ice sounding manner of ice depth sounder null radar type

摘要

(57) Abstract The ice depth sounder of the radar type which adopts parallel Doppler treatment obtains ice sounding of the accurate radar expression whose reliability is higher. This invention, using with the same paradigm as non coherent technology and coherent technology, achieves large signal-to-noise ratio, large signal anti- speckle standard deviation ratio and large signal anti- clutter ratio simultaneously.
