matlab LPC 基于线性预测的参数编码(matlab LPC Parameter coding based on linear prediction)

机械动力学进行模态分析，频响应分析等动力学的分析(Modal analysis, frequency response analysis and other dynamic analysis of mechanical dynamics.)

阵元间频率增量按对数增加，发射波束不再按距离周期性出现，发射波束图最大值只有一个。相较于阵元间频率增量固定的传统频率分集阵列，log-FDA能够抗距离相关的干扰，而且发射能量不泄露，具有一定的低截获性能。(FDA with logarithmically increasing frequency offset to achieve a beampattern with a single maximum at the target location. FDA radar with uniform interelement frequency offset, its beampattern exhibits maxima at multiple range values. doe tu the multiple maxima, a number of reflectors located at any of the maxima can interfere the target-return, thus deteriorating SINR.)

自己编写的，利用模糊数学方法计算船舶碰撞危险度得matlab程序(Self-compiled matlab program for calculating ship collision risk using fuzzy mathematics method)
