　　PPT是针对博主使用粒子群优化算法解决水面无人艇静态、动态障碍物规避，及场地布局三类问题，做了更深入的总结分析。　　与目前火热的机器学习不同，智能优化算法需要对问题建立确定的模型，具有明确的优化目标函数，对优化变量不断的寻优。通过对三种算法的问题描述、模型建立、算法参数确定、算法流程描述、计算结果分析，及从维度、优化变量、优化目标、针对业务的PSO优化四个方面，对应用在不同场景下的三种粒子群算法进行对比总结，旨在更彻底的剖析如何将粒子群优化算法应用到具体的问题中。　　该PPT是原版包含动画的PPT（Office版本越高越好，至少2010，否则有些动画在低版本显示有问题），自我感觉PPT

MOTIVATIONPropeller related acoustic signatures typically exhibit modulationcharacteristics. These modulation characteristics originate from the cavitationprocess that takes place in the water due to the cyclic movement of the propellerThe cavitation process is basically the collapse of air and vapor bubblesdue to variations in the static pressure. These variations in static pressure are aconsequence of the passage of the propeller blades through the water. Thismovement, cyclic in nature, causes amplitude modulation in the static pressureand as a consequence an amplitude-modulated(AM) signal can be detected in areceiverCyclostationary processing techniques have been used to detect andlentify analog and digital communication signals very successfully. Thesetechniques have the advantage of using a more realistic model for the signalthan the stationary model used in most of the more conventional signalprocessing techniquesB BACKGROUNDThe basic elements of cyclic spectral analysis are the time-variant cyclicperiodogram and the time-variant cyclic correlogram. These two functions form aFourier transform pair. This fact is known as the cyclic Wiener relation or thecyclic Wiener-Khinchin relation [Ref. 1: p. 49.1
