The viaual display system of the DLJY shiphandling Simulator is composed of laser vision disc players,special video mixer,multiplex controllable raster,and large screen video projectors, with high speed random access laser vision discs as the storage medium for signals.It is enabled to display dynamical seascape vividly, and also is enabled to exhibit a shore scenery of large visual field for ship maneuvering near by a wharf. It is a new type of visual display for simulator. The mathematical model of this simulator is enabled to imitate the collision avoidance between two ships at day ornight, or by means ofradar. Also, it is enabled to imitate the operation of anchoring and berthing alongside with mooring lines——not more than 4 lines. The DLJY Shiphandling simulator incorporates the features of multifunction, originality and practicability.

A special video amplifier incorporates high gain,large dynamic range and low noise in-to one module,and processes complex signals.The design of such a module,therefore,is fairly dif-ficult.Choosing proper devices is essential,but to make them operating at optimal conditions,de-signing a good signal channel is the key.On the other hand,a high quality amplirler must be char-acterized by critlcal parameters.So,the selection and definition of parameters and related test tech-niques are extremely important.Avideo amplifier module with a total gain up to 90dB and a band- width of 10MC is presented in the paper.The automatic gain control(AGC)for the module is in the range of 70dB.Its output amplitude and noise voltage are 1~8V_(p-p) and 30μV_(p-p), respec-tively.
