Paper Abstract

According to the gridded discrete processing method, the laser echo characteristics in the case of ladder terrain ground are analyzed theoretically, and the ladder-like terrain echo mathematical model are established. We find from the work that these two peaks of ladder terrain echo curve is the reflecting of ladder and ground respectively, the time interval between wave peaks is determined by the mutations height of terrain. The mutations height is higher, pulse shaping is more obvious, it is also shown that ground reflectivity in the laser spot affects the size of the echo peak mainly, and does not affect the peak location on the curve.
