Three problems in Miscel1aneous Sea Clutter Simulation have been dealt with and expounded. The first one is the processing of data obtaiues from Sea Clutter. The Softw are of data processing developed on the basis of least-square method gives the results in three forms-digits curves and formulas. The second one is to depict the build-up of the data base, Diskette is used to store a11 sorts of data with a view to shortening the time of response to cal1s prior to the real-time processing operation by the Simulation. The last one is about the management of the data bank. Here，sorftware is provided so as to facilitate optional retiese and storing of data when simulation process is gaining on.
