基于Android的航海雷达仿真训练系统

The Training System on Simulation of Navigation Radar Based on Android

为了解决航海雷达价格昂贵、维修成本高的问题,适应移动互联网时代用户碎片化的学习需求,设计开发了一套基于Android的雷达仿真训练系统。基于Douglas-Peucker算法,对岸线数据进行简化,并采用扫描线与岸线求交算法生成岸线回波。针对雷达岸线回波生成效率较低问题,提出了图像混合方法有效地提高了雷达扫描的实时性。利用正态分布、瑞利分布、均匀分布对雷达杂波进行建模和仿真,并提出了一种计算机图像裁剪与反裁剪相结合的方法,实现杂波实时扫描更新的效果。基于上述方法开发的雷达仿真训练系统,通过实际使用和对比表明,仿真效果良好。

In order to solve the problem of expensive navigation radar and high maintenance cost,and adapt to the fragmented learning needs of users in the era of mobile Internet,a training system on simulation of navigation radar based on android was designed and developed.Based on Douglas-Peucker algorithm,shoreline data were simplified,and shoreline echo was generated by scanning line and shoreline intersection algorithm.Aiming at the low efficiency of radar echo generation,an image mixing method is proposed to effectively improve the real-time performance of radar scanning.Radar clutter was simulated by means of normal distribution,Rayleigh distribution and uniform distribution,and a method combining computer image clipping and anti-clipping was proposed to realize real-time scanning and updating of clutter.The training system developed based on the above method was proved to be effective by practical application and comparison.
