本舰机动分辨目标左右舷建模与仿真

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

为研究本舰机动分辨目标左右舷的转向角度,分析了本舰机动分辨目标左右舷推理规则可能存在的误判问题。综合考虑敌我运动和转向时间等因素,建立了本舰机动分辨目标左右舷的细化模型。仿真结果表明,本舰转向方向与目标所处舷角方向相反时,分辨目标左右舷所需的转向角度较小;反之,则需较大的转向角。最后,根据仿真结果,利用1stOpt软件进行拟合得到本舰转向后目标舷角最大值和最小值的多项式表达式,并完善了本舰机动的推理规则以更加可靠地判断目标左右舷。

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 lstOpt. Subsequently, the reasoning rule for discriminating port/starboard of a target is improved for more re- liable discrimination.
