| Abstract: | The characteristics of signals reflected for laser bathometry have been analyzed.Bv means ofpreprocessing signals reflected from the sea surface and the sea bottom by gain control,it is realizedthat the dynamic range gain is compressed to 103～104 orders in the PMT GDB-49.The result meetsthe need for airborne laser bathometry. |
