Modeling and Simulation of Mother Ship Maneuver for Discriminating Port/Starboard of Target

To understand the turning angle for mother ship to discriminate the port/starboard of a target, the possible false deduction in the reasoning rule of discrimination is analyzed. A detailed model of mother ship maneuver for discrimi-nating port/starboard of a target is established, in which such factors as the maneuvers of mother ship and target, the maneuvering time of mother ship, and so on, are taken into account. Simulation results indicate that a smaller turning angle is needed to discriminate port/starboard of a target when mother ship′s maneuver direction is opposite to the board angle in which target locates, otherwise a larger turning angle is needed. The polynomial expressions of target board angle′s maximum and minimum just after mother ship maneuver are obtained by fitting the simulation data with the software 1stOpt. Subsequently, the reasoning rule for discriminating port/starboard of a target is improved for more re-liable discrimination.
