往复流条件下灯浮标回旋运动的参数估计

为了分析往复流条件下的灯浮标回旋运动规律，先提出以回旋中心和回旋半径作为定量描述灯浮标回旋运动的参数，然后提出基于核密度的参数估计模型。实验结果表明:在往复流条件下回旋半径参数估计值的波动周期与往复流的周期具有统计上的一致性，参数估计值有效。为了定量描述往复流条件下灯浮标安全领域对航道的占用程度，进而优化灯浮标配布，提出基于回旋半径的航道占用率算法。实验结果表明:在往复流条件下此算法能够有效度量灯浮标安全领域对航道的占用程度，有助于分析和优化灯浮标配布。

Parameter Estimation of Light Buoy Cyclotron Motion in Reverse Tidal Stream

In order to analyze the cyclotron motion pattern of a light buoy in reverse tidal stream，the cyclotron center and cyclotron radius are used as parameters to quantify the cyclotron motion of the light buoy，then a parameter estimation model based on kernel density is proposed.The experimental results show that the fluctuation cycle of cyclotron radius parameter estimation is statistically consistent with that of the reverse tidal stream，and the parameter estimation is effective.In order to quantify the occupation rate of the light buoy safety field to the fairway in reverse tidal stream，and then optimize the light buoy distribution，a fairway occupancy algorithm based on cyclotron radius is proposed.The experimental results show that this algorithm can effectively measure the occupation rate of the light buoy safety field to the fairway in reverse tidal stream，which is helpful to analyze and optimize the light buoy distribution.
